Okay, this is an entry for a contest, and it's pretty much packed with inside jokes. But as long as you've seen/read any of the Harry Potter films or books, it should be somewhat entertaining to you.
The contest was basically to put this guy into the Harry Potter universe, so I threw in a lot of related characters, which is where the majority of the inside jokes come from. If you care to get some backstory, the bottle is a weird talking Vodka bottle, the girl is a character from a Super Famicom game, and Mr. T kicks ass. So rate it however you liked it, and enjoy.
