The guys in fun. have one of the biggest hits of the year with 'We Are Young,' so when Stephen Colbert started putting together the lineup for his own music festival, he naturally turned to the pop trio he dubbed "It on a Stick."

Inviting the band on 'The Colbert Report' to kick off the event, dubbed 'StePhest Colbchella '012,' Colbert yielded the stage to fun. for three songs -- 'Carry On,' 'Some Nights,' and 'We Are Young,' all embedded below -- and sat down with the guys for a lighthearted (albeit not terribly informative) four-minute interview.

Colbert set the tone for their chat early on, noting that two out of three members of fun. don't wear socks, to which singer Nate Ruess responded, "I don't wear socks or underwear -- I don't believe in them," thus kicking off a discussion about where certain body parts might stick without the extra layer of clothing.

Talk then turned to the band's name, and despite initially refusing to answer the question -- "We've been asked that too many times" -- they eventually discussed how "a Swedish death metal band gave us a call ... they said 'We're Fun, you have to change it.' So that's where the period came from." At which point Colbert said he understood why they didn't want to answer the question, because the story was "super boring."

"One of your songs was used in a Super Bowl ad," noted Colbert in conclusion. "Aren't you done now? Why go on?"

"We're doing this right now," quipped guitarist Jack Antonoff. "It seems a little desperate, doesn't it?"
