Come on people...this is the original Nifty Fifty. Well, maybe there were other lenses to go by that nickname...but this is the original Canon EF 50mm F1.8 lens.
While all your friends are shooting with the new plastic 50mm F1.8 II, you can be much cooler and hipper if you're shooting with this beauty. It's got a metal lens mount...it's got a distance scale. You don't even need to shoot with it, to look cool.
