I don't know many, but here's some i herd.
Ricky: Broken bike, broken bones and a broken heart. Damnit!
Hal: Aahoww, i need to get a bigger bike.
Ahow, that sucked!
Vance: Oooooh! Someone check my hair!
Wipeout!
Norton: Stinking bike!
Damnit!
Peanut: Who messed my bike up?
Ow! I landed on my pen knife!
Jimmy: Wipeout!
Um, how'd that happen?
It's just like riding a bike.
Careful, Jimmy.
That.. didn't.. hurt.
I gotta stop doing that.
I'm begginning to like this pain.
That was awful!
Get back up!
Gotta pay attention.
Bailed again.
Not exactly what i ment, but cool in it's own way.
