Someone has made fuh-reakin' awesome t-shirt full of famous movie spoilers.
There's only a few good movies on this shirt, so it's largely harmless fun. :)
Don't click on this link if you haven't seen Citizen Kane, The Usual Suspects, Donnie Darko or The Sixth Sense. Go see those movies, then come back.
Spoilers - the T-shirt
Thanks to Jeffery Overstreet for blogging about this.
