This is a reworking of a very well known puzzle, if you know itpleasedon't give it away.

There are 3 doors in front of you, behind 1 door is a top of the range PC and 52" 3ms TFT monitor, and behind the other 2 are paper bags with rotten tomatoes in.

You are given the option to choose a door, and get to keep whatever is behind it.

After making your selection, one of the other doors is opened which has a bag of tomatoes behind it, and you are given the choice:

- stick with your original door

- switch to the other remaining door

What do you do?
