The "World's Dumbest" crew changes it up this week: We're counting down 20 brilliantly innovative inventions.

The countryside is full of wise people with excellent judgement.

Crime doesn't pay, except in laughs when the criminal is an idiot.

Tru TV is throwing the book at 20 of the stupidest citizens ever to run afoul of the law.

Brilliant performers are rare and exquisite.

Take a vehicle, add an idiot, and the roads get chaotic and crazy.

Twenty idiots enter the ring, but only one will triumph!
