While vacationing in Gansbaai, South Africa, Bryan Plummer decided to take in some world-class cage diving with a bunch of friends.

But just when Plummer thought it was safe to send his recently-married pal Roger into the water in a shark-proof diving cage, along came a Great White with his eyes on the meaty prize.

Plummer describes what happens next:

A shark totally ignores the bait and goes straight for the cage!! He gets his head inside the cage, while fellow diver Roger...acted quickly to swim below the gaping sharks mouth and to avoid any injury.

Apologies for any profanity in the video.. it was an out of control situation.

The profanity can be forgiven, but what a missed opportunity to yell "you're gonna need a smaller diving cage."

Naturally, YouTubers weren't all that impressed with Roger's near-death experience: "Good video but it would've been much better if the shark ate both of the´╗┐ people in the cage."
