You will love this one. In the episode where Drew's barber dies, Drew and his friends notice that Drew's mother is "a little bit too friendly" with the barber at the funeral. Drew then has a flashback to when he was a little kid. The show is pointing out tons of mistakes, (including many in this scene) but when Drew is leaving, he is wearing a Colorado Rockies hat. This mistake wasnt pointed out, and the Rockies weren't around for about 20 more years!
