What happens in Vegas sprays in Vegas.

A 15-year-old boy zipping down the Slotzilla zip line at the Fremont Street Experience on Wednesday sprayed visitors below with his urine, reported a Vegas TV station.

"Like a lot of liquid coming from above us, just showering from head to toe — our back and top of the head dripping down, and we thought it was some sort of water, maybe some drinks or beer," tourist Cazimere Ferguson told KVVU.

So, there's an early winner for year's grossest quote.

Fremont Street officials said the boy's parents apologized, but did not reveal whether the world's worst shower was a prank or a terrible accident.

Either way, we're guessing you'll think twice about standing under a zip line from now on.
