Come back soon for soup

If this gets someone's attention, well it certainly got mine...

I had been playing Pool Jam about ten minutes before making this post.

All of a sudden the screen blanked very quickly (bit like a browser redirctor, but different) presenting me with nothing except a small matchstick-type figure standing in a doorway in the middle of the screen, with the slogan 'Come back soon for soup.'

The hole thing lasted only a split second or so, almost subliminal. Has this happened to anyone else?
