On Thursday night's episode of Late Night, host Jimmy Fallon and his guest Carrie Underwood reflected on their apparent past traveling during the '90s as a singing duo called Jim Carrie. They supposedly would translate rap lyrics into country songs for a mix called "c'rap." That Jimmy Fallon always keeps things interesting!

"People loved us," Fallon explained, hardly able to keep a straight face, audience laughing. "They kept demanding more music from us."
