What SNL sketch centered on a door-to-door predator inspired by Jaws?

The SNL sketch centered on a door-to-door predator inspired by Jaws is “Land Shark.” The character is a shark that knocks on apartment doors, disguises its voice, and tricks residents into letting it inside.

Land Shark first appeared in the season-one sketch “Jaws II,” broadcast on November 8, 1975. Chevy Chase provided the character's voice and played the shark in its earliest appearances, while the surrounding scenes spoofed Jaws through characters modeled on Chief Brody and Matt Hooper.

The joke depends on the shark's absurdly transparent deception. It claims to be a plumber, a flower deliverer, or even a “dolphin,” then attacks as soon as the victim opens the door. The recurring bit parodied both Jaws-style suspense and the conventions of television horror.

Land Shark returned in several later sketches, including a Halloween cold open and appearances involving Gilda Radner. The character also resurfaced in SNL's 40th-anniversary special, where it attacked Tina Fey during a Weekend Update tribute. The Luvahs, Toonces, and Mr. Bill are separate recurring SNL creations.
