Dancing with the Stars

8 p.m., ABCDown to the final four: Derek Hough and model Joanna Krupa (she is doing far better than any model has ever done on DWTS, which leads me to believe she is not that good a model); singer Mya and Dmitry Chaplin (he of SYTYCD fame); serial rehabber Kelly Osbourne and Louis van Amstel; and Donny Osmond and the very likeable Kym Johnson. I'm so happy former boy bander Aaron Carter and Karina Smirnoff were booted, because a) he is about as creepy looking as they come (Lurch, anyone?) and b) she broke my sweet Maks' heart.

The Big Bang Theory

9:30 p.m., CBSThe continual pitting against/pairing of Penny and Sheldon in this season is what is making it so great. Either the writers accidentally happened upon this greatest of ideas and then realized what was happening and stuck with it, or they did it on purpose because they are really good at what they do. Either way, the show is at its absolute best when Sheldon and Penny are in conflict. Actually, when Sheldon and anyone are in conflict, but really, Sheldon v. Penny is like Tyson v. Spinks (June 1988). Fast, furious and great to watch. Tonight, "Penny is forced to rely on Sheldon when she is injured while Howard, Leonard and Raj are away." I'm predicting a knockout (to continue the boxing metaphor).

Inside the Actors Studio

8 p.m., Bravo Bon Jovi alert! Bon Jovi alert! Bon Jovi alert! Tonight, "Jon Bon Jovi, Richie Sambora, David Bryan and Tico Torres discuss their 26-year career and their personal struggles along the way." This is why I love/hate "Inside the Actors Studio." Because while it is true that Jon has done some movies and TV (Moonlight and Valentino - and really, his hair did all the acting in that - U-571, Ally McBeal, Sex and the City, to name a few), the other boys have not. Music videos and the current band "documentary" don't count. But who cares. I love them.
