>SAG Awards (TNT/TBS, Jan. 28, 8 p.m. ET) Yay! Another occasion to put on my fancy nightgown and pretend I’m part of the glitterati. Until I spill salsa all over my lap.

Heroes (NBC, Jan. 29, 9 p.m. ET) If you love guest stars, this is a good week to watch TV. Here, we see Star Trek’s George Takei play Hiro’s dad.

Ugly Betty (ABC, Feb. 1, 8 p.m. ET) Katharine McPhee plays herself at a Mode runway show. Be nice to Betty or we won’t buy your CD!

30 Rock (NBC, Feb. 1, 9:30 p.m. ET) Paul Reubens gets laughs as a foreign prince, but the always stunning Isabella Rossellini, who plays Jack’s ex-wife, steals the show.

Jack’s Big Music Show (Noggin/Nick Jr., Feb. 2, 12 p.m. ET) Real life daddy-of-two Jon Stewart steps in as—surprise!—a fake reporter covering Groundhog Day on the hit preschool series.
