Attention, geeks! Bravo nerded out last night by pairing up the stars of two of the most popular fanboy franchises out there, Star Trek and Buffy The Vampire Slayer. Spock himself, Zachary Quinto, appeared to promote the upcoming Star Trek Into Darkness, while Alyson Hannigan showed up to shill… well, How I Met Your Mother, probably, but inevitably she spent most of her time talking about a show that’s been off the air ten years.

And even if it’s been a decade gone, that doesn’t mean some juicy backstage drama can’t still perk our ears up. Alyson took no less than three jabs at the slayer herself, Sarah Michelle Gellar, over the course of the show.

Watch after the jump!

For six glorious years, Buffy the Vampire Slayer ruled the airwaves and was one of the most popular shows on TV. It's been 15 years since Buffy started staking vampires in Sunnydale -- and a lot has happened since then to the stars of the show!

From marriages to children to high profile drug arrests (oh yeah, and plenty of other acting roles too), the famous faces of Buffy have kept themselves quite busy! Check out what Sarah Michelle Gellar and the rest of the cast have been up to these days!
