The parable of, "Hit me baby, one more time"

A man named Dennis was walking down the street and asked every person he met, "I want to hit you in the face. My right fist I have nick-named ‘Mr. Conservative’, and my left fist I have nick-named ‘Mr. Liberal’. Which fist do you want me to use to smash your face, Conservative or Liberal?"

And amazingly, everybody chose a fist! Even one really huge, muscular dude, asked to be hit with Mr. Conservative, but didn't strike Dennis back because he reasoned that "he had asked to be hit and chose a fist, so they had a valid contract for services".

A really attractive young lady saw all this and came up to Dennis and asked, "How would you like to be hit in the face? It is really mean what you are doing. So, now I'll ask you, 'What hand do you want me to hit you with, Mr. Conservative or Mr. Liberal’?"

Dennis gave the obvious reply. "None! I don't want to get hit period!"

The attractive young lady, obviously amazed with Dennis' commonsense intelligence, rugged good looks, and sexy body, asked Dennis out on a date.

They lived and loved in happiness … for a while anyway, until the young lady grew a cancerous, mutated, third arm, growing out of her chest, where her heart should be. She nick-named her third arm "Mr. NDP".

Dennis ran for the hills!
