If at first you don't succeed...

If, hypothetically speaking, none of my previous ideas of escaping the city sound appealing than I've got one more suggestion: go see a movie.  Granted prices for moviegoers have gone up substantially (especially now that the cashiers skeptically eye me when I claim to be a youth, but it does still work occasionally), nothing beats munching on salty movie popcorn while sipping on a slurpie and losing yourself in the cinematic action.  If you crave something more check out a drive-in theater, which (to this day) is one of my favorite parts about going home.  Otherwise check your local papers for special events, for instance I was able to catch Dirty Harry in Bryant Park, which was a really fun atmosphere - just make sure to get there early in order to get a good seat and bring a blanket!
