Like a bad haircut that works only when you part or tie your hair a certain way, You Don't Mess with the Zohan is funny only sometimes, for two-minute segments, leaving you with long, almost surreal stretches in between in which you are wondering whether what you are watching is really that bad or so brilliant that you're just not getting it. It doesn't take long after the funny, promising 20 minutes—which include a fresh, funny and increasingly ridiculous fight sequence—to realize that the filler that takes up a considerable chunk of the two-hour comedy is, well, just that.
