This technique was mentioned in the movie, "Clerks."

If Ms.Hdog said to me, "I know that I never gave you head before we were married, and I've never given you head since we've been married. I would be willing to do it, but only if you let me give you a 'snowball," I would agree to it.

Of course, then we'd both just start laughing because, well, sh!t, it's Ms.Hdog we're talking about here.

Either that, or her head would spin around and she'd vomit up some pea soup. Or an alien would pop out of her chest. Or my alarm would go off. Or....

But yeah, I'd do it (as long as I get to chase it with something, like maybe a beer).
