You still need reasons why you shouldn't throw away your 3D glasses after the movie is over? Check out all the sweet 3D shit I did today:
1.) Saw My Bloody Valentine in 3D.
2.) Loitered for 20 minutes and saw Milk in 3D.
3.) Went for a walk.
4.) Went home and looked at the Internet.
5.) Took a nap.
6.) Brushed my teeth.
Do NOT throw these away. You can see the whole world coming at you.
