For most of her career, Mariah Carey has had a reputation for being a humorless diva, but in the last few weeks, the Hello Kitty-obsessed superstar has proven there actually is a funny bone in that famously curvy bod, and she’s turned in some of the funniest moments of the year. (And in a shift from her notorious attempt to serve ice cream on TRL, she’s in on the joke this time!) First she delivered two hilarious, over-the-top speeches at the Palm Springs Film Festival and the People’s Choice Awards; now Mimi is continuing her comedy tour by prank-calling her hubby Nick Cannon. Posing as “Debbie” from Merrick, Long Island, Mariah called in to Nick’s radio show, “Rollin’ With Nick Cannon,” and all she wanted to discuss were the merits of porn. Take the jump to find out why Mimi—er, we mean “Debbie”—thinks pornography is the “humdinger.” (Her words.)

Listen to the whole hilarious interview blow and try not to be charmed by Mimi’s plalyful antics yet again:

“Me and my husband have a very good time when we watch porn,” Mariah deadpans in a thick Lawn Guyland accent as Nick cracks up, still not realizing that he’s cackling at his own wife. “And I don’t think it’s bad, and I think it were bad, then it wouldn’t exist. And I think everybody should experiment with porn.” Carey then uses a few words that can’t be used on the radio to describe a man’s… accoutrements, if you will.

“So you use porn as like a gauge system?” asks Nick.

“A gay, what?”

“No, a gauge.”

“A geisha? Who? No, I’m talking about porn, like real hardcore stuff… C’mon Nick, you know you look at porn.”
