OK so in a drunken state, my friend (NO it wasn't ME!) used this line in a bar.

The girl was sitijg on a stool by a ledge and he walked up to her and said "I think you stole my stool" and you should have seen the look she gave him. Freaking hilarious! needles to say it was a massive failure! I wish I got in on video, it would be one for youtube for sure.
