::Jesus Christ, why are people so thick. It's like this.. 
 #Choose a door; you're lucky it's a goat! but you had a 2/3 chance of choosing a goat so the odds were on your side. 
 #Monty reveals the other goat. 
 #You switch; it has to be the car as the other goat is gone. 
 #You win! 
 #If you had chosen not to switch you would have lost; by not switching you're stuck with that 2/3 chance of getting a goat. 
 #End of.
