Person A: "You're cranky, aren't you?"
Person B: "No, I'm not cranky! How dare you suggest I'm in a bad mood. Listen, you skulking, flea-ridden excuse for a biped, I'm not in a bad mood, and if you don't shut the hell up about it, I'll rip your spleen out with my teeth! Now honey, would you hand me a section of that newspaper?"

There was an hilarious episode of Roseanne once...
We all make jokes about painful things - that's one of the main reasons why we have a sense of humor - to get through the hard times. If we can't make them go away, we might as well find a way to laugh at them. I liked your poem/song - is there a tune?

While PMS exists, I'm sometimes just in a rotten mood just because. I wonder what men blame rotten moods on. Probably women. ;-)
