Remember ten years ago when those Big Mouth Billy Bass singing fish were everywhere? You don't see them much anymore . . . but now they're FIGHTING CRIME.

If you're not familiar with the Big Mouth Billy Bass, it's a motion activated plastic fish mounted on a plaque, that moves around and sings annoying songs.  It also has button you can push to make it sing and dance.

Well in Rochester, Minnesota a burglar broke into a fishing store. The store had a Big Mouth Billy Bass on the wall near the door.

As the burglar broke through the door, he knocked the fish down. And when it hit the ground, it started singing AL GREEN'S "Take Me to the River".  You can catch the video below.

Apparently, that SPOOKED the burglar . . . because he dropped the stuff he'd planned on stealing and ran out.  Police are still looking for him.
