T.R. Knight shows his range ... on "Sesame Street"

Now that our daughter is 3 (and not sitting in my lap drinking from a bottle), I haven't been watching as much "Sesame Street" as in the past. But yesterday was different. We were both home sick -- she from preschool, me from ... here ... with the same toddler-delivered cold, and who did we see making an appearance in the world of Big Bird and Elmo? Yes, "Grey's Anatomy" fans, it was T.R. Knight.

For those living under a rock, Knight recently announced that he was gay, prompted to do so after being the subject of an on-set fight between "Grey's" co-stars Patrick Dempsey and Isiah Washington in which the latter hurled a gay slur.

Enough of that drama. Back to "Sesame Streeet." As you can see in the picture above, Knight played a private "I" in the episode (bet you can guess the letter of the day). In the noirish skit, Knight searched for the missing letter in such words as -guana, -nsect and -ce cream. Being dressed in a giant foam letter "I," of course, is the clue he needs to determine the missing letter. Glad I explained it, aren't you?

Since it is a noir fantasy, and Knight is a detective, there's a mysterious blonde moll involved. And yes, their eyes meet and ... get your mind out of the gutter -- this is a show for 3- to 5-year-olds!

Well, if you missed the episode, remember this: "Sesame Street" films about 26 episodes per season (covering, at the minimum, all the letters in the alphabet, although in decades past the number of yearly episodes was much higher). It airs twice a day on weekdays, once on Saturdays. So in the next 30 or so weeks, that gives 450 chances to see it ... over and over again.
