The comedy duo Key & Peele in a sketch that’s Hogwarts meets The Wire.

Other great sketches of theirs: dubstep, civil war reenactors, “I’m retired”, and dungeons & dragons.

Key & Peele also have a fun, meta YouTube series where they critique their own show, in character. If you’re wondering more about the duo, there’s a good interview with them on Marc Maron’s WTF podcast. (last two links both a bit NSFW)
