When a guy wants to talk to a girl but he doesn’t know what to say to her he asks her if she has ever run a friction crane. Nobody really knows what a friction crane is but it is a way to start a conversation.

Girl: Whats that?
Guy: I don’t know but I thought you were pretty and I wanted to talk to you.
Girl: Whats that?
Guy: I don’t know but I thought you were pretty and I wanted to talk to you.
