Had a guy a few years ago decided he wanted to dance while I was conducting my interview. He bowed up and took a swing and I curled hip up against the wall with his left wrist pressed squarely against his right shoulder blade. He yelled a bit and as I started to release the pressure he shouted get off me you ain't my father. In good fashion, I applied a bit more leverage, leaned in close and whispered in his ear, the only reason you're so angry is because you don't know if I'm your father or not.
Last I heard he was doing a nickle for assaulting a public safety officer, and I have a funny little story to tell. Guess I won out in that one.
