In the early 90's Karma got jumped by a car load of Nortenos, in broad daylight, and got hit in the head a few times with a 2 x 4. As the story goes, Alan Petersen ran away, to his credit he probably assumed Karma ran too and wasn't being whacked in the head with a length of wood.
One time someone sarcastically asked Karma for his autograph to which he responded 'Yeah, my knuckles on your forehead'.
