Could Turn Into a Good Series
Most of the humor came from stuff directly from the games (Peach and the cake, Toad and his mushroom hat, Birdo, etc) and that's the stuff that worked the best. Using Birdo was a brilliant move, that was about the one thing I wasn't expecting though the ass humor in that scene went on a little too long I think (once you brought up the eggs it became clear what was going to happen and in that case it's best to just get to the punchline like you did with the Peach not puting out bit). The Michael Jackson thing didn't really work but if you stick to the other humor that's rooted in the game you'll have a great series on your hands.
