Neil Patrick Harris, the hilarious Barney Stinson on "How I Met Your Mother,"  turns 39 today. NPH has made us laugh for the last 7 seasons of his show where he plays a womanizing and clever schemer. NPH was also a teen-hearthrob in the late '80s and early '90s in Doogie Howser M.D., when he played a teen prodigy and the youngest doctor in history. The show was his first big TV success. NPH will reprise his role as Barney when HIMYM returns again for season 8.

Hope you enjoy your birthday, Neil!
