Its not a juice joke, but if you get it its still funny.
3 Dudes on top of a 100 story building on a lunch break, 1 white, 1 latino, 1 black guy. They get bored and decide to see whose dick is the longest, so white guy goes first. Pulls his dick out, slams it on the ground BAAAM!! It goes to the 75th floor, he's like yeeeaaah bitches!!
Latino goes next. Pulls his dick out, slams it on the ground BAAAAAAAAAM!!! It goes to the 50th floor, halfway down the building, he's like oooorale cabrones!!!
Black guy goes last. Pulls his dick out, slams it on the ground BAAAAAAAAAAAAAAM!!!!!!!!!! Waits a few seconds and then he starts to move quickly from left to right, shuffling his feet like the MC Hammer dance. Finally the other two guys are like what the hell are you doing??? Black guy answers, I'M DODGING TRAFFIC!!!!!!!
