Conan O'Brien and Chelsea Handler, late-night cable rivals in the 11 p.m. time slot, decided to strip down to butt heads (and something else) over studio space on Wednesday night's "Chelsea Lately."
Conan returned to his old "Tonight Show" studio for the first time since his messy split with NBC to confront Handler with a few gripes in the staff shower -- the same place actress Sandra Bullock lectured Handler about her late-night responsibilities with the "fancy new stage" last October.
"This is my studio. You stole it, remember?," Conan says after Handler asks how people keep getting into the shower. "I still have the key, plus this is the best water pressure in Hollywood."
"And you stole my parking space. The parking space I had here is four inches wider than the parking space I have now," Conan said. "You also took my back massager. I loved that back massager and I left it in my office. I bet you use it every day."
"I do use that back massager," Handler responded. "Although I had no idea it was for my back."
Both eventually end up with black eyes, but since there's no subtle way of explaining how, it's best to watch the clip below to find out.
