Great issue (even if it didn't have a photo of Melinda). Re Flim Flam: I of course agree with Mr. Farmer and Ms. Savant, that you should always switch. I prefer the following explanation. As soon as you have picked a door, you are probably wrong, as you did not pick the 2/3 left. All Monty is doing you is showing you which of those 2/3 has the goat. To make the example more understandable, suppose there were 100 doors. As soon as you pick one, you are probably wrong, this time because you didn't pick from the 99/100 left. If Monte opens 98 of those doors and shows you all goats, and you STILL don't switch, then please come to my house and bring money.
For those who still can't make the stretch, with only 3 doors you can quickly map out all possible outcomes of where the car starts, where you pick, and what happens if you switch or don't switch. You can very quickly realize that you should switch, always.
