yup there is a line of movies about this...it is called "big sausage pizza" and stars people like ava devine, whom procedes to blow and screw the pizza delivery guy after he makes his delivery
That's an old joke. It was in an early Tom Hanks movie called Batchelor Party I think over 20 years ago. In that one the guy sticks it through a tray onto a hot dog bun.
I think it's stupid. I'd rather get laid then eat the pizza.
