Two tigers walking down a trail. Suddenly the second tiger leans forward and licks the butt of the tiger in front.
The first tiger turns, slaps him, and says "stop that".
A moment later the second tiger leans forward licks the butt of the first tiger again.
The first tiger stops and says "what's wrong with you? why do you keep doing that?"
Second tiger says "I ate a lawyer an hour ago and I'm trying to get the taste out of my mouth."
