Singer John Mayer served as the guest host for The Late Show on Wednesday and had the blue sharks that danced at the Super Bowl with Katy Perry as guests.
The sharks -- who became a viral sensation after Perry's halftime performance -- were accompanied by Carl Thorson, the Lead Marine Biologist at the Harrington Institute of Oceanography and the creatures' agent.
"I guess my first question is for the sharks... what's it been like to see this turn into such a national media event?" Mayer asked. "Did you expect this to become the phenomenon that it has?"
Mayer asked the fish, only to be told by Thorson that they couldn't talk, because, they're sharks. When Mayer followed up with questions about the left shark's seemingly uncoordinated performance, Thoson explained why it happened.
"In the wild sharks normally swim in pairs," he said. "Naturally there's an alpha shark on the right, and the clumsier, dumber left shark... sorta flops around like a sidekick,' the scientist explained. 'But no less important."
The shark's cameo during Mayer's gig appears to be another confirmation that the singer is back together were Perry. The couple was spotted on dinner dates at least twice in January and posed together for a photo with Missy Elliot after the Super Bowl.
