I wasn't surprised that South Park jumped on the bandwagon this week (you can watch the full episode here.) Their "Elementary School Musical" was spot-on, and brilliantly used the existing songs with a twist in lyrics. If you haven't seen the movies, it's probably not as entertaining. But even though it's been a while since I spent any quality time with Cartman, Stan, Kenny and Kyle, it was nice to see they haven't lost their spark.

The more unexpected HSM treat came in the form of Bruce Willis on Letterman last night, who was on to tout his cameo appearance alongside teen heartthrob Zac Efron. I'm not sure I can accurately explain the clip that Willis brought with him, but it is pretty entertaining, and Willis' thoughts on his "role" are pretty creative. He's done a true character study.

Check out an excerpt from South Park and the clip of Letterman below, and then let us know what you think. Game on!
