Everyone younger than 40 (and many older) knows Nintendo. From its arcade roots with Donkey Kong, Popeye, Playchoice 10 (remember? play a NES for 25 cents!) and many more to its console days from the NES, SNES, N64, NDS, and now the Wii - we all have played and loved Nintendo video games and have a place in our hearts for that wacky plumber, Mario.

Here we present to you some of the best unofficial Nintendo-inspired T-shirts. See if you can figure out which game each one comes from.
