Well, I remember back in 1993, there was this asshole who was trash talking everyone in the video arcade about how great he was at Street Fighter 2.
So I walked into my arcade (yes, I was young and territorial), and said, "you look like just another Ken player to me."
He raged. Hard. Demanded respect.
So I asked him to prove it, and decided to up the ante ... best of five, winner never visits that arcade again.
To make it even more interesting, I said, "how about pub rules? Get double perfect'ed, and you gotta run around the arcade 3 times with your pants down."
I got him 3-0, with a double perfect in the third game.
My buddies blocked off the exit until he did what he agreed to.
Who says shit like this only happens in movies?
