"Splash" (7 p.m., KSTP, Ch. 5), which was entertaining for about three dives, closes the pool with a two-hour episode in which all the contestants return for a final jump. That means our own Louie Anderson will once again get a chance to show off his one-of-a-kind swimming outfit.
I wish I could tell you that "Reel Rivals" (7 p.m., Weather) was a reboot of the old Siskel and Ebert act. Instead, it's yet another fishing show, this one about tourists trying to catch game fish in the Florida Keys.
Picking up the bill
"Constitution USA With Peter Sagal" (8 p.m., TPT, Ch. 2) continues Twin Cities Public Television's winning streak of documentaries about early American history without triggering a severe case of the yawns. Sagal is our amiable Harley-riding host, visiting with Americans about their interpretations of what the forefathers really meant. Clever animation adds to the fun in this limited series.
