Florida man catches 400-pound Goliath Grouper fish with a wrench

His tool of choice: a DIY wrench lure. It's a wrench, string, and two fishing hooks. With only this tool, Florida man Ryan Hein was able to reel in a 400-pound Goliath grouper while fishing in the St. Petersburg area.

Dude's a mechanic.

"A lot of mechanics know that you don't really use an 11 for anything," Hein told a local news reporter. "At least I never have."

"Some jigs can cost $20," he said. "I was just looking for a way to make a jig without spending so much money."
