On The Final Hole
Sometimes while golfing the guys behind you become impatient and will yell stuff at you for taking your sweet time or may just hit their balls before you are even done with the current hole. Here is how you get back at them, on the final hole (which is sometimes the hole that decides their game final score) wait until their balls are hit. Then dash over to their balls. Pick them up, throw them over the fench, get in your golf cart, and head for the exit.

Beer Shower
Toss full cups of beer into the air on a dance floor as soon as the club goes dark from timing with the beat of the song. Then check out the dancers reactions as they go from energetic happy partiers to pissed of beer coated victims as soon as the light turns back on.
