ROCK ON DOMESTIC MUSCLE!!
Nice kill, i hate people that are full of crap. A solution could have been:
"...fine, i can appreciate that you have to work on the morning. Tell you what then, we'll run on the way to your house so you can go to bed and we can see just how badly you pull on me..."
Sensible challenges like that work. Say infront of a crowd aswell. If he backs down, he looks like a moron and loses his credibility and nobody will respect him. Great way to teach morons a lesson.
