Buffy's 13 today: Watch the rare pre-debut teaser trailer

Has it really been 13 years to the day since Buffy the Vampire Slayer debuted on The WB? Seems like yesterday, and yet Mar. 10, 1997, was so long ago I didn't even remember (don't hate me now) that the series launched as a midseason replacement!

If you were there from the very beginning, you first met Sarah Michelle Gellar's Buffy Summers not in the show's first episode, but in a teaser trailer that's only aired twice.

Check out the promo below to see how the world first met the Slayer—though the embedded clip is missing the warning that "The following two-hour world premiere is rated TV-PG and contains action scenes which may be too intense for younger viewers."
