Big Bang Theory — Last week’s episode, “The Hot Troll Deviation” was the one where we found out why Howard had been dumped by his girlfriend, Bernadette. Turns out Howard had cybersex with a troll character on World of Warcraft (Howard is a wizard, natch) and Bernadette walked in on them. The best part of the episode was the recurring presence of Howard’s visions of Katee Sackhoff and George Takei, who got to not only give Howard a hard time about his sexual proclivities but also interact with each other. This show just continues to deliver solid laughs every week, in spite of the laugh track. And this week’s show gave us a little more of Johnny Galecki as Leonard, whose screen time sometimes suffers in the wake of Jim Parson’s breakout status.
