Ok this one I just chose myself.
I dare Jasper to lick 5 cars

Jasper: What's a car?
Me: Those big boxes with wheels.
Jasper: Do I really have to lick 5 of them?!?
Me: Yesh
Jasper: Here we go!
Jasper first licks Greg's van, then Mayor Dewey's campaign van, then the pizza delivery car, and two other random cars.
Jasper: *wipes off tongue*
Lapis, Peridot, and me: *snickers*
Jasper: I'M GONNA POP YOU TIGERS EYE! *charges at me*
Me: OH CRAP! *runs out door*
