N64 Expansion Pak
When I was a kid, it seemed like everybody had an N64. I think it was because of Perfect Dark or The Legend Of Zelda: Majora's Mask, but everybody also had to buy the Expansion Pak for it. One of my friends had an unofficial one, and when I saw his N64 it looked so stupid! It was sticking out the console making it look like a spaceship! I had the official one, where it fit flush in the connector and you could close the lid after installing it.
