"SNL" parodies VP debate with help from Usain Bolt

"Saturday Night Live" parodied the vice presidential debate with a little help from the world's fastest man.

Jamaican sprinter Usain Bolt dropped by the NBC sketch show's mock debate after Taran Killam, playing Mitt Romney's running mate, Paul Ryan, claimed he won the 100-meter race at the London Olympics. Ryan has been criticized for exaggerating his marathon time.

"SNL" had fun with the vice presidential candidates following Thursday's contentious debate. While President Barack Obama and Romney's first debate didn't offer as much obvious satire, the show happily skewered Vice President Joe Biden and Ryan.

Jason Sudeikis, as Biden, called himself "Big Daddy Joe" and insisted he was "monkey strong" unlike his younger foe, whom he referred to as "shark eyes." Killam played Ryan with an Eddie Munster-like widow's peak. Moderator Martha Raddatz, meanwhile, was portrayed by Kate McKinnon.

The Biden character kept laughing at the Ryan character. "I'm sorry Martha, but with all due respect, this is malarkey," he said laughing." When the moderator asked, "A bunch of malarkey? What does that mean?," he responded, "Um, it's Irish. No, Irish is I come over there and smack that dumb look off your face."

Actress Christina Applegate also guest-starred on the sketch comedy -- first taking on the opening monologue before performing a song and dance number.
