Fox's Dushku, Michelle Pick Bad Week for Letterman

David Letterman often seems indifferent at the desk -- especially when sitting across from guests with whom he's not particularly familiar -- in the best of times. But his two interviews this week with pretty young women -- "Glee's" Lea Michelle on Monday and "Dollhouse's" Eliza Dushku on Tuesday -- were especially awkward.

The host seemed distracted in both cases, a complete stranger to both of the Fox series (he told Dushku he's asleep when he isn't doing his program) and perhaps -- and maybe I'm projecting here -- uncomfortable being juxtaposed visually with beautiful young women in extremely flattering dresses while conjecture swirls around him about who he might have slept with on his show's staff.

Both nights, notably, Letterman's monologue was quite funny. But you have a feeling for the foreseeable future that what comes after that will give a pretty good indication of what sort of toll having his private life exposed is exacting upon him.
