What's on: Sunday

Sunday shows are trickling back with new episodes. Watch HBO's ROME (10 p.m.) winding down (or up) to its series finale, which is supposed to be next week.

And, as if his administration wasn't a big enough joke, Arnold Schwarzenegger appears on THE APPRENTICE (NBC/10 p.m.).

Also new: CBS' Amazing Race, Cold Case and Without a Trace; two episodes of FOX's The Winner; NBC's Grease: You're the One That I Want; Sci-Fi's Dresden Files and Battlestar Galactica; Showtime's The L Word; MTV's I'm from Rolling Stone; E!'s Girls Next Door.
