"Remember the Big Mouth Billy Bass? You'd press a button (or trigger a proximity sensor for a surprise) and the fish would start singing either Al Greens Take Me To The River, or Bobby McFerrins Don't Worry, Be Happy. Jeff Foxworthy once quipped that if you had more than three singing fish, you might be a redneck.

Texan Richard Carter took a Volvo, 5 miles of wire, five 6-volt golf cart batteries, a screw drive mechanism using 12v DC reversible motor, a lifting frame he made from scratch, a Linux server and approximately two hundred synchronized singing fish, and created what can only be described as an awesomely effective assault on good taste."
