 Welcome back to the School Class Sense. It's Challenge Tuesday, and you may have guessed it isn't Tim. Tim's been taking that, giving me that much stick from my ponytail that I decided to get in a new coach, a better looking version of Tim that has rocking apparently. So this is Lyle. Hi, I'm sympathised now. And we are going to do today which she's going to challenge me. She's gone, Jack, I'm going to take you on, on the world's slowest pike push-up. So what it's going to be is you're going to comment below to challenge a friend, and you're going to do this as a head-to-head against each other. So Lyle's going to be on that side, I'm going to be on this side of the line. Don't you come on my side. And it is going to be the slowest person back up is the winner. So the last person wins rather than the first. It's like you're first, you're like, you seem to have a day and a night. No, I haven't. Ricky Bobby. Sorry. Harvey Haslow, Harvey Haslow. You're first, you're last. Now on this actually you're last, you're first. It's the opposite of Ricky Bobby. Don't make any sense. So tag your friend in your comments below and then set up your camera, and then you've got to be last. So pike push-up. Up on your tiptoes. Right, and you've got to make sure he's not cheating, Harvey. I never cheat. Right, bum nice and high and then we go in. I'll give you a three, we'll go three, two, one, then we start. Ready? Three, two, one. Always moving, always moving. No stationary points. Don't you be checking. I'm trying to look forward to the check. You got down yet? Head hits the floor, must touch the floor. Slowly back up. You can't stop still. I think I'm... Is she still moving, are they? Is she moving? Is she stationary? I'm flipping, I'm nearly there. I'm there. What we're having really, what you need. Is you need an adjudicator. You need an adjudicator. So we'll obviously watch this one back. I'm just going to go with the assumption that I won. We'll go and look back at the tape. But that's this week's challenge Tuesday. Challenge your friend, the world's slowest... Pike push-up. And we look forward to seeing you. Til next week. Class dismissed.
