Taylor Lautner sure got a kick out of hosting Saturday Night Live.

In the New Moon actor's opening monologue, he used his years of martial arts training to behead a Kanye West mannequin for heckling "really close" friend Taylor Swift as she accepted her Best Female Video award last summer.

In the skit, Lautner, 17, says he wished he'd stuck up for Swift, 19, on the VMA stage as he presented her with the award.

"What I really wanted to do was this," Lautner deadpans, as he starts wielding a sword and karate kicks a West mannequin, beheading him.

"You are the bravest man I've ever known," a high-pitched voice intended to be Swift's, says before Lautner goes in to kiss her cardboard likeness to close the scene.
