"Stop, drop, and roll." Maybe have the character be on fire after messing with fireworks, or a lighter, or something of that sort?
"Pelvic Thrust" Need I say more?
"Squat Dance" Its on Wikipedia and lots of youtube videos of it.
"Banana Peel" the character is eating a fruit of some sort and drops it on the ground... gets distracted... and comically slips on it.
