With movies like Smash His Camera heading the Sundance must-see list, celebrities should know by now that people are watching, even while they’re attempting a sneaky faux pas. Ben Affleck (The Company Men), Paris Hilton and Tommy Lee Jones apparently thought that open bar included service, choosing to stiff their bartender at a Deer Valley party. (Maybe they thought the dollar bills others dished for their drinks were for the local’s good looks?)

Fortunately, Elijah Wood (The Romantics) had a different idea at a party across town. Enraged that his compadres hadn’t anted up for the tip at a local restaurant, he began collecting cash from his buddies to make good on the grat.

Karma will thank him for that, but taking the cake in celeb generosity was without-doubt Bill Murray (Get Low) — who went so far as to ask his waitress what she might want at the end of the evening. When she replied a foot massage, he obliged, rubbing her tired tootsies right there in the restaurant.
