GIGGLETHROTTLE

Yesterday I did something that I’ve never done before: I snuck into a movie.  

I’d just paid for and watched The Girl with the Dragon Tattoo, which was excellent by the way book fans, and then slipped into The Artist, which was as amazing as everyone says. Seeing as I’d paid $13.50 for a film that would have cost half as much in the ‘burbs to go see (or that would’ve been if I were SAG),  I felt obliged to get my money’s worth.  

My question is this: How common is sneaking into other films? Do you do it? And if you do, how often?
