Roberta Vinci went on Italy’s Sky Uno entertainment channel recently. She sat down to chat, and then collided on a tennis court of sorts with host Alessandro Cattelan, who is also the host of her country’s “X Factorprogram. In tried and true (read: clichéd) talk-show fashion, the host put his guest to the test of guessing various grunts’ originators. This time the question in play was this: Tennis or pornography?
