Punch me in the face

It's another work nite. I'm discussing with a girl about whether the chicken parmesan is good or not. I told her that I liked it, and she accused me of possibly "just saying that." I told her no. It's actually good, and I eat it plenty. Then I gave her my guarantee; evidence of my sincerity. "If you don't like it, you can come back and punch me right in the face."
