The show's captain, Kate Mulgrew, begins a four-episode stint tonight on Syfy's entertaining Warehouse 13 (9 ET/PT) as a Warehouse regent who has a secret past with one of the agents — and a bold plan for saving the under-attack Warehouse.

•MTV launches two series, starting with Ridiculousness (10 ET/PT) an amateur video clip show starring Rob Dyrdek, who introduces the videos and mocks the amateur participants.

If that sounds like Tosh.0— or America's Funniest Home Videos, or The Soup, or Web Soup— well, welcome to TV. As they say, it's all in the execution.

•Then comes the premiere of Death Valley (10:30 ET/PT), a scripted COPS-type show that follows the LAPD's Undead Task Force.

In case you think that reflects bias against vampires and zombies, they also take on werewolves and other un-undead monsters.

•Or, if you prefer, you can team Syfy's Warehouse 13 with TCM's sci-fi classic: Forbidden Planet (10 ET/7 PT).

Walter Pidgeon, Anne Francis, Leslie Nielsen (in his pre-Airplane serious phase) and Robby the Robot star in this loose adaptation of Shakespeare's The Tempest.
