Two guys are in a strip joint, one is sitting in front of the other. A woman comes on stage and starts stripping.
The guy in back, Paul, says, "Oh yeah, Oh yeah!"

Then the first guy turns around and says, " Hey Paul, shut up!"

Then two women come out and start stripping. Paul, once again, starts, "Yeah baby..mmmm....yeah!"

Once again the guy in front turns around and tells Paul to be quiet. So three women come out and start stripping. Paul is silent.

The guy in front says, "Hey Paul, where's all your excitement now?"

Paul says, "All over your back!"
