Open Question: Is this a normal thing to do when I'm mad?

Ok, well I've always wodered WHY I do this.. This is what I do.. When my dad and I get into a heated arguement, and he's about to explode into a million pieces and I feel like I could fall off a cliff and not feel scared, that's how mad we are. When we are THAT mad like imnnot een kidding kinda mad, and we start yelling at each other and stuff, no matter where we are, I always end up laughing.
