A look at tonight's sci-fi TV:
Better Off Ted, "Battle of the Bulbs" - Tonight's episode sees Ted and Linda duking it out over who can build a better light bulb – his lasts forever, and hers features "aromas ranging from zucchini bread to fresh laundry," so its anybody's game, really. What we're really excited about is tonight's guest spot from News Radio's Khandi Alexander. She plays Lem's mom, a super genius scientist with a disturbing crush on our favorite underused character, Dr. Bhamba. (9:30 p.m. on ABC)
Outer Space Astronauts, "Vast Empitness" – In a possible nod to Star Trek's most popular illegal beverage, Romulan ale, Ka'ak serves up some mystery alien moonshine that leaves the crew with a hangover from hell. (11 p.m. on Syfy)
