"I don't know what's going on," Jimmy says, confused, in the Jimmy Kimmel Live birthing class sketch.

"So your vagina needs to open up, Jessica explains. "Well, it's technically your cervix..."

"I have trouble getting my vagina open," Jimmy says.

"Well, you don't have trouble getting your mouth open," Jessica snaps back.

"Well that's true," Jimmy agrees. "I'll try to think of it as my face vagina."

And then Jimmy learned what a perineal massage is and you don't want to miss his reaction to that!
