Adam Levine dumps manure on Blake Shelton's truck

Rocker Adam Levine stunned fellow The Voice judge Blake Shelton during Monday night's (12May14) show by dumping manure on his pick-up truck.

The audience and the show's stars watched footage from a camera stationed outside the studio during a live episode of the singing contest as two bulldozers unleashed piles of poop on Shelton's red truck.

The prank came two weeks after Shelton tweeted Levine's cellphone number during a show.

The chuckling Maroon 5 star said, "I thought I would return the favor, why not pay him back a bit. That is cow dung, that is faeces of animals."
