Conan O'Brien poked fun at Justin Bieber over a recent video of the singer peeing in a mop bucket with a new spoof video called "Bieber Whizz."

The parody aired during Conan's TBS show Wednesday night and featured a janitor being questioned about how he got his floor looking so good. And there's only one place to get it.

Footage of Bieber urinating in a mop bucket in the kitchen of a New York City restaurant earlier this year made its way to the internet on Wednesday. The singer's pals urged him to do it, saying that it was "the coolest spot to piss" and that he'll have that memory forever.

Justin addressed the incident vaguely on his Twitter page, writing, "In life u will make mistakes and people will try and tear u down...but u gotta stay positive. Stay strong..and learn to be better..and.. ...always live to serve others and The Lord. #growingeveryday."
