Watch it

“Who is Clark Rockefeller?” (9 p.m., Lifetime). The based-on-a-true-story about a German con man who successfully impersonated the heir to the famous American family. It’s a Lifetime movie, so come on, you know what you’ll be getting. But it stars Eric McCormick, who should elevate it to better-that-it-should-be status.

“Saturday Night Live” (11:35 p.m., NBC). If last week’s show with Zack Galafianakis was hit-and-miss, how can this week’s show with Jude Law be any funnier? But Pearl Jam is playing, and they always put on a good live show.

Skip it

“Dinoshark” (9 p.m., Syfy). A hybrid dinosaur/shark terrorizes a Mexican beach resort, and only a young fishing boat captain can save them. I feel 0.6% stupider just by typing that.

Hoop it up

There’s a bunch of good college basketball today, as 11 NCAA Tournament teams will be decided in conference tournament finals. The best of the bunch:

Pac-10 finals: Cal vs Washington (3 p.m., CBS).

Big 12 finals: Kansas vs. Kansas State (3 p.m., ESPN)

Big East finals: Georgetown vs. West Virginia (6 p.m., ESPN).

ESPN2 has the Big West finals at 5 p.m., and the WAC finals at 7:30 p.m.

The Big 10 semifinals are on ABC starting at 10:30 a.m.; the SEC semis are on CBS starting at 10 a.m.; the ACC semifinals tip off at 10:30 a.m. on ESPN. The second semi for each of those tips off around 2:30 p.m.
