Seen this movie about 8 times, recently in the theaters which was great. Hands down, without question, a perfect movie. Okay, it sure does seem easy to knock someone out with just a punch, but who cares. It's hilarious, action packed and the characters are well thought out and funny from their own specific point of view. It's what every "reluctant buddies on the run" movie strives to be but none have ever touched. Perfection.
