Carol Burnett will be guest-starring on the March 17 episode of Law & Order: Special Victims Unit. Holla! She’s set to play “a former dancer caught up in the murder of a young couple,” which…Okay. Burnett has played scary villains before — anyone else still haunted by Miss Hannigan nightmares? — so we’re expecting her icy best, especially because SVU luh-luh-luh-loooooves having famous guest stars play superfreaks. Highlights include Martin Mull as a mean doctor who tells his patients that HIV doesn’t cause AIDS, Mark-Paul Gosseleaar as a reluctant porn star who’s the victim of a gang rape, Bob Saget as a creepy possessive husband who microchips his cheating wife, Matthew Modine as a rapist/murderer who escaped the strong hand of justice years ago, and Fred Savage as a slimy neighborhood rapist. And those are just the ones I can remember off the top of my SVU-filled head. I think my favorite might have been Robin Williams, who played a disturbed anti-authority activist. He represents himself at his trial, and I particularly enjoy his “don’t be a sheep” closing argument:

After the jump, easily the dumbest scene in SVU history. The monkey’s in the basketball! Which ones did I miss, PopWatchers?
