A character has suffered an amusing injury, usually of the blunt force to the head variety. Dazed, he will say something really random and Non Sequitur, normally either before going out like a light or... PUNCH! And THAT, my good senator, is why your brother likes to live on the wild rice, and won't eat his track and beans! THUD!
Self Demonstrating / Non Sequitur, *Thud*
