This is very gross, and not just glancingly so. We have Wegman’s often and even usual situation, where we keep looking to figure out what the heck he’s doing. The conclusion is unexpected, and funnier because of it. If he’d started this series of little films with this one then we could well suspect him of just being a jerk. Putting it at the end of the reel, and in light of what’s gone before (and in light of what will follow), we just remember that boys will be boys.
