At the costume party

A couple of psychologists decide to throw a costume party. They agree that they must have a theme, and agree that everyone should come dressed as an emotion.

On the night of the party, guests began to arrive: The first couple came dressed in red… as anger.
The second couple came dressed in blue… for depression.
The third couple came dressed in green … for envy.
The guests had a good time, but all of the costumes lacked originality.

At the stroke of midnight there was a thunderous knocking on the front door. They answered the door to find a huge man completely naked, except for a tire hanging from a huge chain around his neck. He was fully aroused, his manhood jutting through the middle of the tire.

Shocked, they asked him what he thought he was doing.

He said “I’m here for the party, I’m fuckin’ da spare.”
