Out of sight could mean out of mind, so NBC's trying to remind everyone that Conan O'Brien's coming back to TV in a couple of months by airing some new promos, available at ew.com. The first one features Tina Fey; Conan did a guest bit on a first-season episode of her sitcom "30 Rock," "Tracy Does Conan," which happens to be Talk Show News' all-time favorite. "I am a stabbing robot!" "What am I, a farmer?" "Mind grapes." "Blood cookie." But we digress. The second one stars Megan Mullally.
