Happy 35th birthday to T.R. Knight, our favorite man in blue scrubs. He's somehow managed to juggle being smart, adorable, and incredibly sexy (he came in all the way up at #8 on the AfterElton.com Hot 100 List). When he was going through the difficult outing process, he earned our respect and admiration for keeping it together while things behind the scenes of Grey's Anatomy were falling apart. Here's hoping that his BFF Katherine Heigl and his...slightly younger boyfriend Mark Cornelsen have some special surprises in store for him tonight.

In case you've never seen it, after the break here's a clip of a very young T.R., in an instructional video about problem solving...at work. (oh, the irony). I'm not sure when this video was made, but judging from his cute feathered hair, and the ancient computer behind him, my guess is the early 90's.
