I loved the first one, and couldn't wait to see the next one. Most of its humor is either racial, sexual, or drug-related, so if you aren't into that, steer clear of this one. If you can appreciate that type of humor you will be laughing throughout the entire movie. It is also filled with many ridiculous "wtf" funny moments, reminiscent of the cheetah scene from the last movie. The movie itself isn't offensive, but a lot of the characters are, and Neil Patrick Harris returns once again and really stole the show for me. Some of the jokes are derived from the first movie, so I really recommend seeing the first one before you see this to get acquainted with the characters. So go grab some friends and get ready to laugh, one of the funniest movies of the year!
