The three worst jokes that I heard in Vegas:

1. 185 shoes walk into a bar. The bartender says "We don't serve your kind here". One of the shoes says "Hey, that's lacism".

2. 185 cartons of milk walk into a bar. The bartender says "We don't serve your kind here". One of the cartons says "Why not?". "Because you only tip 2%."

3. 185 Michael Jacksons walk into a bar. The bartender says "We don't serve your kind here". Michael Jackson says "I just came in to use the little boys room".
