What’s on Tonight: Duff vs. Dushku

Community (NBC) — Hilary Duff guest stars in a Mean Girls-like episode that also features Pierce (Chevy Chase) getting hurt on a trampoline. Oh, and in case you were curious: last week, in the 8:30 spot with a strong lead-in, “Community” actually got good ratings. What a surprise.

The Big Bang Theory (CBS) — Squaring off against “Community,” “BBT” answers with a sexy guest star of its own: geek goddess Eliza Dushku.

It’s Always Sunny in Philadelphia (FX) — I’m woefully behind on this season. I have a bad habit of trying to have a social life on Thursday nights, then coming home and only watching “Community” before going to bed, leaving a couple hours’ worth of new TV unwatched on my DVR. But hey, you want a full-time TV reviewer, you gotta pay full-time reviewer money. My bank account says I’m only getting blogger dollars*. (*minimum wage + Camel Cash)

Bones (Fox) — “So You Think You Can Dance” star Stephen “tWitch” Boss guest stars to help dumb down the credits.

CSI: Original Flavor (CBS) — Larry Fishburne and the CSIs investigate a murder in which the body has been shredded to bits. “And I guess that was your accomplice in the wood chipper.”
