Oh, so the guard was deaf. I didn't like this as much as most people. I guess I'm not into Metal Gear parodies that much. It doesn't help that I'm not familiar with the games. I still thought this was pretty funny. The best part is probably how the animation moves so well.
Okay, that's an overstatement. It's quite cheesy, but it works so well that way. I like the little things that pop out. The funniest part was probably him asking where the buttons are. It was just a nice cartoon.
