Jon Hamm To Voice Don Grouper On SpongeBob SquarePants

Hamm, who recently won an Emmy for his role as Don Draper in Mad Men, may have said goodbye to the AMC drama, but he’s not leaving Don Draper behind just yet. In an upcoming episode of Nickelodeon’s beloved cartoon, Hamm will voice the character of Don Grouper, an ad executive at “Grouper, Goby & Koi,” who arrives in Bikini Bottom to help Mr. Krabs advertise his frozen Krabby Patties.

Grouper is described as having a “sharp mind and devastating charm [that] make him an irresistible force. When Don’s in the room, everyone laps up his words like overpriced organic honey.”

The episode is currently scheduled to air sometime in 2016.
