My Dad played the first SMB with me all night when he got me an NES for my 5th b-day. Sonofabitch kept playing after I feel asleep too, and beat the first Bowser before falling asleep himself. The next morning, I went to wake him up, and he barely opened his eyes and said, "I beat the dragon guy, finally..." and fell back to sleep. At 5 years old, I was pretty damn impressed. He also beat Tetris on the original GB at the highest setting before I ever did. I remember him shouting at me to come see the rocketship taking off.
