Thumbs and Ammo: All Thumbs, No Guns

Say no to guns, say yes to thumbs. You can't kill anyone by pointing your fingers at them, but you sure as hell can make them laugh if you know how to use your digits. Heck, I know I'm laughing at these skillfully Photoshopped posters and stills from renowned movies of yesterday and today which star the likes of Harrison Ford and Jack Nicholson.

Even Chuck Norris isn't spared the all-thumbs treatment. Check out the gallery and the blog that started it all, Thumbs And Ammo, for more thumbs up action!
