A PRANK involving fake poo and one of the world’s most expensive cars has gone horribly wrong.
Czech pranksters Erik Meldik and Cenek Styblo were not impressed when they were allegedly cut off by a motorist in a Lamborghini, Channel Nine reports.

So, as a joke, they reportedly decided to place fake faeces on the bonnet of his sports car as payback.

But they never expected what happened next.

Upon spotting Styblo, who was pretending he’d just finished doing the deed on his car, the victim pulled out a taser.

“Hey, what are you doing to my car? Get the f--- away from my car,” he says.

“What the f--- is this? You think that’s funny?"

The man then fires the weapon at Styblo, who runs and falls to the ground in pain.
