Someone at the local theatre has some brains -- they scheduled a guy flick to start 5 minutes after Mamma Mia all day long. So, we went to the movies this morning, and he did NOT have to suffer through the chick flick. Everyone's happy.
I'm not going to do a spoiler, but STAY FOR THE FULL CREDITS. Someone a couple rows in front of me left early, and I had just heard the door open when the whole theatre burst out laughing. I'm sure they're now regretting that they didn't stay to find out what was so funny.
