Wikisimpsons - The Simpsons Wiki
Bart: Dad, why are we doing this?
Homer: You've always afraid of falling on your head ever since you were a little baby. I'm trying to help you overcome that fear.
Bart: You want me to jump because I've always been ... jumpy?
Bart jumps...
Homer: [laughs] That's a good one son. Always been jumpy! [laughs more]
...Bart lands on his butt because Homer was laughing too hard.
