Late-night TV also saw Seth Meyers reunite "SNL" alums Fred Armisen, Will Forte and Jason Sudeikis to perform a sketch that never aired.

On Late Night, Seth Meyers got the old Saturday Night Live gang back together to perform a sketch Will Forte had championed, but which never made it to air.

On CBS, Jim Parsons revealed he had no idea who his The Big Bang Theory boss was when his agent called him about the part.

"I did not know Chuck Lorre at the time," Parsons said. "I thought he was talking about Chuck Woolery," referring to the Love Connection host.

Jimmy Fallon hit a high note with country singer Dolly Parton, who is celebrating 48 years of marriage. "I've only had one husband but with all the plastic surgery, he swears he's been with three wives," she joked at her own expense -- before convincing the Tonight Show host to try on her wig.
