I learned the following verses:
Baby Sharky
Mama Sharkey
Papa Sharkey
Grampa Sharkey (use closed fists insted of open hands for the "no teeth" effect)
Bible Sharkey (open hands side to side like a book)
Dudes a-surfin (one arm behind and one in front like you are balancing on a surfboard)
Babes a-tanning (face up and arms out to the side to get a nice even tan)
Shark attack!
Pieces floating (hand down your head, lean your torso forward a bit and let your arms hang)
Lifeguards coming, too late!
Oddly enough, this was my brother's favorite camp song after he learned it.
He was 19, and never went to camp.
