The average movie ticket price is still like $6.50 or something. Don't ask me where since my girlfriend paid $10 for each of our tickets, but it's still the average (even matinees are like $7.50 here). Honestly though, I'm confident 90% of you badmouthing Baby Mama didn't see it. It was seriously funny.
Okay, let's use the $6.82 figure that BOM quotes for this year, although I think it'd be assuming way too much to think Baby Mama was as successful in areas with cheap theaters compared to areas where prices would high. That'd still mean only 2.6m people saw the movie over the weekend.
