To analyze this problem we represent this senario as a random variable on a roulette wheel. The roulette wheel on the left simulates the Let's Make a Deal game. The inner wheel represents the number of the door that the car is behind, the middle wheel represents the door that is selected by the contestant, and the outer wheel represents the door Monty Hall can show. Spinning this roulette wheel once is equivalent to playing the game once. The outer wheel also tells you what your strategy should be to win. The red means that in order to win the contestant needs to switch doors, and the blue means that the contestant should not switch. Notice that there are twice as many red sections as blue. In other words, you are twice as likely to win if you switch than if you don't switch! What this wheel makes evident is that with probability 1/3 the contestant selects the correct door in which case it would be better not to switch. In the other 2/3 of the cases, Monty Hall is telling the contestant where the car is!
I still can't seem to wrap my head around this explanation, but the evidence confirms it. If you manually go through the game enough times and record the outcome of the choices you will find switching yields about a 66% success rate. Too bad the show is off the air.

Sunday mornings waking up at 5:00 a.m. Strapping on the boots and winter clothes. Fumbling around with the shoelaces. Everything quiet outside from the fresh fallen snow. Cold weather stabbing at the lungs. Bending down to untie the stack of newspapers. A cold breeze going up my scrunched up coat. 10 Sunday newspapers fitting into the bag at a time. Fitting them in between screen doors and quickly slamming the door shut before they have a chance to spill back out of the door. Walking back to the newspaper stack and down another street trying to remember who is on vacation this week. C0llecting the money once a month and heading down to the comic book store. Finding out some of the comics are now worth $1,250.
Back in the Dirty Mitten. It has basically been snowing nonstop since I've been back. It made my first bus late by 8 hours. Today we are supposed get 12 inches. What to do on snowy days? Take in a movie!
