As a happy owner of the Nintendo Entertainment System growing up, I know all too well the frustration when the NES wouldn't recognize my game cartridges. My trick, learned from friends, was to blow the cartridge connectors with all my might. It always worked... eventually.
I spent years blowing my Nintendo cartridges and always assumed that's how I got the game to load. Then, earlier this year, I learned the horrible truth. Blowing my Nintendo game cartridges did absolutely nothing. In fact, Nintendo claims the moisture from my breath helped ruin the games.
I wonder what other stuff I believed was actually total bullshit...
