When my gf and I get into a fight it's pretty hard for us to stay mad at each other because she'll usually say something silly and we'll both start cracking up. Case in point, the other day we started arguing about something I did or didn't do, I can't recall exactly what it was but she was pretty pissed at me. Towards the end of our little spat she demands "say apologize." Despite having learned from past experience that I have a better chance at winning the lottery than an argument with the gf, I can't resist digging myself into a deeper hole and mutter "apologize."
Not surprisingly, punches ensue...I guess I'm a masochist : )
