Variant on the original is the rodeo. When you're nailing the girl from behind, tell her shes the fattest cow you've ever tossed one into.

Variant on the prior is the full staffed rodeo. Two friends need to be in the closet dressed as rodeo clowns, one preferably video taping the ride. They hop out and steer the angry cow away from you after she bucks you.
