Knocked Up is hands-down the funniest movie I've seen all year.  I laughed so hard a few times, I actually cried.  It was great!  The comedy starts at the beginning and never lets up.  It's over 2 hours long, but it surely didn't feel like it.  And it's definitely NOT for kids...with the language and some graphic scenes.  I recommend this movie to any adult who likes a good laugh, and isn't offended by vulgar language.

My favorite line was "Now THAT'S how you get pink eye".  Absolutely hilarious.
