Once Upon a Time Rosario Dawson Built a Penis Slide and Vagina Tent at Burning Man - VIDEO

What happens at Burning Man stays at Burning Man. Except for STDs. And stories that Rosario Dawson tells about giant genitalia replicas she made.

Dawson was on CONAN last night (March 26) when talked turned to the musical festival.

Apparently she has done projects several times, one of which was surrounding that year's theme: Rites of Passage.

Which prompted her to create a "penis slide" which led you into a "misting vagina tent" to recreate the greatest rite of passage, being born.

According to the actress, the slide was covered in giant fake sperm and to escape the vagina you had to find the G-spot. Which was a button that made lights flash and a doorbell go off.

Just like when you're born?

We think our favorite part is Conan O'Brien's face because it looks like he's so done.
