You guys, I'm nuts for this picture. (

Bad puns aside, I had to share with you this too-cute photo, which was snapped on the set of Katie Holmes' new movie, Mania Days. The movie is being filmed in NYC, and it's her first major flick since splitting with Tom Cruise.

City squirrels can be major cray, so I salute Katie's bravery in this moment. I don't think I would ever dare get that near a squirrel, furry friend or foe.

Whaddya think? The funniest pic or the funniest pic?
