I was once at an arcade having a great game on Kung Fu Master (a game I was never any good at until that day) and had never beaten the 4th floor boss. FINALLY I got to him and started kicking his ass. I kicked off his head (had lots of energy) and he grew another without making the "copy" of himself. I started gut-punching the hell out of him and was about to finish him off.. when the game froze. S**T!!!
Another time I was going for a record I was going to submit to Nintendo Power magazine for Super Mario Bros. I had MILLIONS of points, over a hundred lives, etc. I was playing this in the den, and the wiring was all screwed up.. the light switch at the bottom of the stairs from the living room turned off the television and NES. We had relatives over and their kids, and one of them (about 4 years old) sauntered down the stairs and turned the light switch off. UGH!!!
