What we're watching: Heat vs. Pistons of course, the premiere Eastern conference rivalry plays out once again as time ticks down towards the playoffs. The Heat are shorthanded with Jason Williams and James Posey injured, so Dwyane Wade and Shaq will have to pick up the slack at 8 p.m. on TNT. Also, the game is at Miami, so crowd watching in high definition is highly recommended.

Elsewhere, NBC has committed the terrible sin of replacing The Office with Teachers at 9:30 p.m. so don't be fooled. Instead, if you didn't get enough Debra Messing during Will & Grace, switch over to HBO and check out The Wedding Date.
