The alien man and human woman are about to get frisky when she looks at him and says, "Gosh...it's so big!"

"If you like," replies the alien, "you can make it bigger by pulling on my ears."

So, she pulls on his ears and, bing, it gets bigger.

The next morning the aliens leave and the human couple are talking. "Well, honey," says the husband, "how was it?"

"I just gotta tell ya," she says with a faraway look in her eyes, "it was the best I've ever had. How 'bout you, was it good?

"It wasn't worth a damn," he says. "That bitch was trying to pull my ears off all night long!"
