Tigger

Christopher Robin: You're next, Tigger. Jump!
Tigger: Er, jump? Tiggers don't jump, they bounce.
Winnie the Pooh: Then bounce down.
Tigger: Don't be "ridick-orous". Tiggers only bounce up!
Christopher Robin: You can climb down, Tigger.
Tigger: Ah, but tiggers can't climb down, uh, uh, because, uh, oh... oh their tails get in the way!
Rabbit: Hooray! That settles it. If he won't jump, and he can't climb down, then we'll just have to leave him up there forever!
