When the shark approached the 37-year-old swimmer and chomped down on his leg, Cull didn't panic.

Instead, he busted some serious slapstick-style eye-pokeage all up in the shark's face, the AFP reports.

"It banged straight into me, and it grabbed me by the leg and dragged me under the water," Cull said.

"I just remember being dragged backwards underwater. I felt along it, I found its eye and I poked it in the eye, and that's when it let go."

Note to self: Pokey fingers are like kryptonite to giant, hungry sharks.

Cull got away and was pulled to safety by a beachgoer.

He had some chunks taken out of his leg, but he is expected to recover.
