Ask This Old House Experts Give Jimmy Tips for Toilers, Critters and More | The Tonight Show

Our next guests have made over 1,000 house calls to homeowners across all 50 states on their Emmy-winning series, Ask This Old House, my favorite. Its 25th season is airing now on PBS. 25th season. And it's streaming free on the Roku channel. Please welcome Richard Trethewey, Kevin O'Connor, and Jen Nawada. Hi, Jen. Welcome back to the show. Congratulations on 25 seasons. Yeah, that's a lot. That's unbelievable. What did you bring for us today? So we've got a couple lessons for you, and the first one's going to be potty training. Thank you. And Richard has a toilet with your name on it. Let's go, buddy. It's right there. All right, Richard, we can do this. Richard, you are the plumbing and heating guy. What do we have here? Where do you want me to go? Right here. Okay. So this is a toilet, and it works on a basic... Principle of physics. Simple physics is called a siphon. And it means that you have to have two things, a short leg and a long leg. Okay, so the water gets pushed up here, that creates the short leg, goes over the hill, and all of a sudden, this longer thing creates the long leg, and it'll pull out all the contents. Now, so a siphon you can use to drain a hot tub, a pool, a tank, without a pump. It works every day in a toilet perfectly. That's how I get gas. Absolutely. Yeah. So here, I've got a little demo to show you the magic of a siphon. So here's the tank, and when we flush the toilet, the tank itself pushes the water up the short leg. So here's the short leg. Here's that long leg. But what we need, Jimmy, is a negative pressure. We need to be able to pull on this pipe right here. So what I'd like you to do, if you could, would be to just, so now you have to have enough to pull it up the short leg, okay? So give it a try. Here we go, we got this, come on! That's how it works. That's good. That works. I'm soaking wet. Thank you. Richard, thank you very much. I appreciate this. Thank you very much. Jen, what do you have over here for me? Well, sorry about that. No, please. I want to play a game that you, I think you've played before. It's called What Is It? Okay, yes. I like What Is It? So, it's long, it's black, and it has a lot of knobs. Uh... Is this like one of those, maybe it's a Christmas, like a laser thing? Like one of those things you get at Home Depot? That's creative, that's creative. Like a 15-foot skeleton or something? You put this and it broadcasts like the Griswold house on your house? Or is this like a, I know what this is. This is a wine opener. I've seen one of these wine overs. Yes. Yes. They're $15,000. They're very hard to come by. What is this? Actually, it is a motion activated critter deterrent. So let me show you. Yeah. I know you've been into vegetable gardening. I have been. Yes. You value your tomatoes. I'm known for my veggies. Yes. Yeah. So you want to protect those with everything. Thank you. Let me just show you. I have an animal. Animal. Oh, Richard! Richard, I'm glad that they're making you do this, Richard, because he's Richard. Oh, my God. Oh, my God. Thank you very much. I love that you made Richard do that. All right, well, Kevin's got one more to show you. I love that you made Richard do that, because they probably wanted me to do that at one point. Come on over. Kevin, all right, what do we got here? We're going to teach you to fell a tree, but we want you to be safe, so Richard and Jenna are going to get some safety gear on you. But while they do... Why do you have to embarrass me every time you come on? Go ahead, go ahead. It's just unbelievable. Okay, thank you very much. So if you're going to drop a tree, you want to make sure it falls in the right place. And to do that, you've got a couple cuts. So this is the face cut right here, and it's two slices so that you create a wedge, and then this comes out. So this is now the direction of where the tree is going to go. Then you're going to come with a back cut right here, and you're going to come through until you get to right about there where that intersects. And that's going to cause the tree to lean and eventually fall in that direction. I always wondered how that works. Yes, you're up for it. I mean, I'd love to do this. How do I, what do I... here we go, a chainsaw, a chainsaw for you? Yes, let me get this set up for you. So you're gonna do this. All right. It's a real chainsaw. It's a real chainsaw. So two hands. What are you going? What is wrong with you? Three. It's totally safe. It is, right? It is totally safe. So two hands. Two hands. One here, one here if you cut down. One here, one here if you want to cut across. Okay. Okay, I'm going to take the brake off right there. Yeah. Now, one hand there, one hand there. Yeah, this is a real chainsaw. It's a real chainsaw. No one's ever allowed me to use a chainsaw. I can't believe NBC's letting me do this. Right there. Yeah. Two fingers to get the trigger going. So thumb and an index finger to start it. Pick it up. Be careful. Off the table. OK. You good? Yeah. And? Yeah! I can't believe you're letting me do this. All right. Can I have a pass? Yes. What do I do? All right. Safety eyes. Are you ready for this? Yeah. Come with me. Come on. Come with me. We want to put you in the holiday spirit. Oh, wow. It's the Christmas season, Jimmy. Come on. Can we get a little Charlie Brown? Get a little Charlie Brown in there. A little Vince Guaraldi. Wow, look at this. You want to take this down? Oh, my God. This is, honestly, I've never done this. This is amazing. You're going to be all right. Okay. Your tie's tucked in, your mask's on. Yes, I hope so. So I've already made the face cut. You can see it right there. You're just going to make the cut in the back going like this. Okay. We'll get you all set up. Get that. All right. Step up to the tree. Two hands, two hands. Yep. All right, let's get the bar break off right here. All right. Now, tip it sideways. The bar brake is on. You're horizontal. There you go. You stay away from me now. Take a knee in. I got you. Be careful. Now, you're going to get it started, and you're going to get the bar right at where that B is. Will you watch your finger, Kevin? You're good. Right behind that V. Come in it nice and slow. Holy mackerel. This is the manliest thing I've ever done. You'll drop this tree in a flash. Come on, bud. Get in there. Merry Christmas! Nice and flat. Look at that. Come on. Safety first! Safety first, you remember that. The best! Are you kidding me? You guys are the greatest. Come on. My thanks to everyone from Ask This Old House! 25 is airing now and streaming free on the Roku channel. We'll be right back, everybody!
