'SpongeBob SquarePants' Sneak Peek: It's 'Happy Days' in Bikini Bottom

We all know Fonzie was the big fish on Happy Days, but now Henry Winkler is swimming with the sharks. In this exclusive sneak peek from the brand new SpongeBob SquarePants episode, “Sharks vs. Pods,” Winkler voices Sharkface, a tough guy who grew up on the mean streets of Bikini Bottom. And as a bonus, he’s joined by two more Happy Days alums, Michael McKean and David Lander, who played Lenny and Squiggy on the Happy Days spinoff, Laverne & Shirley.

For their meeting with SpongeBob (Tom Kenny), “The Sharks” seem to have borrowed Fonzie’s leather jacket and Squiggy’s hair grease. And if you think Fonzie knew how to whip a comb out of his back pocket, you should see the hair-grooming products this shark trio pulls out!

Take a look at the clip and see the Fonz jump the shark — or at least turn into one.

The “Sharks vs. Pods” episode of SpongeBob SquarePants premieres Wednesday, May 4 at 5:30 p.m. on Nickelodeon.
