Watch it

Kentucky Derby (1 p.m., CBS). They call it the most exciting two minutes in sports. But today it’s really the only two minutes you need to bother turning on your TV. So fix yourself a milt julep (don’t forget to muddle the fresh mint) and check it out. The race actually starts around 3:25, so if you want to skip the tedious pre-race stuff, tune in around 3.

Tune in and feel old

“Accused at 17” (9 p.m., Lifetime). The title says it all. But it stars Cynthia Gibb. I had a big crush on her back on her “Youngblood”/”Fame” days in the early ’80s. Now she’s playing the mom of a teenager. Sigh.

Skip it

“Star Wars” marathon (beginning at 12:30 p.m., Spike). It’s all three prequels, so don’t bother.
