Thumbs And Ammo is a blog with a bunch of user submitted movie stills/posters with the weapons removed from the characters' hands, and thumbs-up poses instead. It just goes to show, you don't need to be waving a gun around to look like a badass, you just need to know how to pose. One hand on your hip, in general, is not the way to go.
Hit the jump for a ton more, but check out the blog for so many I lost count (so over 30).
Thanks to PYY and Josh C, who agree the Fonz is a perfect example of how throwing the thumbs up can make you look like a badass. Also, a leather jacket and cool hair doesn't hurt. Still, Josh -- you're gonna have to work harder if you want to get in my good graces like your buddy Tallon.
