If I wanted to, I could probably do a TV tech quiz for How I Met Your Mother — you wouldn't think, but this ensemble of friends in NYC is pretty wired — especially my favorite character, Barney. I've Ioved NPH since Doogie Howser, MD, and as Barney I love him more — he's got an iPhone, a MacBook Pro — and talks in tech (and text) speak 24/7! A little bit creep but a lot of geek, Barney killed me in this clip from last week's episode after a scandalous romp with Ted's ex-girlfriend Robin.
