It just stands to reason that a show with a name like Buffy the Vampire Slayer wouldn't have a terribly serious set. And with cast members like Nicholas Brendon, "serious" seems to be a completely foreign concept. Every set has its prankster, and Brendon is happy to step up to the challenge.

"Would you call putting sugar in someone's gas tank, or burning the left wing of someone's house down a prankster? Well if that's a prankster, then I am." Brendon proclaims it proudly, as if he's got a Boy Scout merit badge for arson. "It goes back and forth: me and Seth [Green, who plays Oz], me and Seth, me and Seth, me, me, me, me, me, Seth. Sometimes Tony [Head, who plays Giles] gets in on the action, but they pretty much sit back and watch me and Seth make fools of ourselves."

Of course, an actor's job isn't all fun and games. It's also nudity. When asked to choose a favorite, of all the girls Xander's been involved with in the series' run, he's swayed by his favorite episode, "The Zeppo," arguably one of season three's finest.

"I'm just going to have to go with a little bit of Nick and a little bit of Xander. Faith. Because, uh... we were having sex, right? 'Cause I was there. And they just put little pasties on her because her top kept falling down. So I'm saying Nick and Xander 'cause I saw pretty much the whole kit 'n' caboodle."

Sex turns out to be a subject near and dear to Brendon's heart. As pointed out in "The Zeppo", Xander is surrounded by supernatural beings: vampires, slayers, werewolves and witches. As the single run of the mill human left among Buffy's circle of friends, what kind of supernatural creature would Brendon want to play Xander as?

"Invisible," is his first idea -- a surefire way to cut down on the 16-hour work days by phoning in lines. But he changes his answer in mere moments to "sex demon," which is a thought that brings a smile to his face.

The possibility of Xander crossing over to the new Angel series also touches on the subject of sex. While it's doubtful that Xander and Angel -- characters at odds since day one -- will ever get along, Brendon's got secrets to reveal there, too.

"I'm supposed to be going on Angel in episode 16, and we make love." His delivery is completely deadpan, and for a moment you almost believe him, but the gig is up when that completely irrepressible grin emerges again.

Television -- even with both series in the mix -- probably won't be the extent of Brendon's involvement with Buffy, either. There's the rumor of a Buffy feature film... not to be confused with the original Kristy Swanson flick that spawned the series.

"We do five years and do a movie, or we do seven years and possibly do a movie. I know Joss wants to do another one [Whedon also wrote the original movie], we all pretty much want to, and it's just our schedules and Joss' schedule and eighteen million dollars to do it. That's how much it costs to make a movie, to do it proper."

He's even got his own ideas for future Buffy episodes... though they could be considered rather unorthodox. "It would be me. There'd be some girls. An anteater. A family of possums. And a Mug root beer. Now, how it all works together I'm not really sure. But those are the key components."
