Two friends go into a bar...

Friend 1: "Please don't try anything funny. I don't wanna get kicked out like last time."

Friend 2: "Hey, I was really funny back then. Not my fault they didn't get the joke."

Friend 1: "You? Funny? Really?"

Friend 2: "Yeah I am. If I said 'Boo', I bet all the ghosts in the room would laugh."
