The first game I can remember coming out is the Legend of Zelda for the NES, I saw the commercial of the guy in the room freaking out of the monsters in the game. When I saw the commercial I was about 8 or 9 I thought the game was going to be retarded because of the commercial, I was so wrong.(see below)

I did not see this one at all back then but it is pretty funny.
