The "Celebrity Trifecta" is complete

Doogie Howser M.D., aka Neil Patrick Harris, is gay. My first reaction?

Duh.

But I do find it interesting that in less than three months, three male celebrities have come out (or been outed, depending on who you talk to and how you look at it). Lance Bass, T.R. Knight (George from Grey's Anatomy), and now Harris. Do these things always come in three?
