Long before How I Met Your Mother's Barney invented the Lemon Law and other fantastic dating techniques, Neil Patrick Harris was just a young fledgling doctor trying to make his move on hot older gals. Sure there was dream gal Wanda, but check out this old school episode of Doogie Howser, M.D. where the teen heartthrob dates a Laker girl dancer. Before you suit up to watch NPH on a long awaited, by me at least, HIMYM episode tonight, take a look back at just how adorable he was way back in the '80s. And you've got to love how geekily dorky Vinnie Delpino is. He's like an earlier and more heavily accented Marshall... kind of whipped but willing to engage in elaborate schemes in order to seem cool.
