On a certain game show, five families were asked to match famous names to faces they were shown, and each correct guess got one point. The families made the following guesses (in order):

The Addams' guessed Otto, Roebling, Steinmetz, Tesla, and Westinghouse.
The Bunkers guessed Tesla, Westinghouse, Otto, Steinmetz, and Roebling.
The Cunninghams guessed Roebling, Tesla, Steinmetz, Westinghouse, and Otto.
The Flintstones guessed Tesla, Roebling, Otto, Steinmetz, and Westinghouse.
The Jetsons guessed Tesla, Westinghouse, Steinmetz, Otto, and Roebling.

No two families got the same number of points. Which family walked home with the grand prize?

The key is to note that they're associating 5 names with 5 pictures, so it's impossible for anyone to get exactly 4 right (cause at least two must be switched).  Thus, since everyone got a different number of points, there was one family with each of 0,1,2,3, and 5 points.  In particular, someone must have gotten them all right.  Then it's a matter of trying each family's answer as the correct one, and looking for families with the same score.  The only case where all families have different scores is if teh Flintstones get 5 points.  Thus, the Flintstones got the prize (hopefully a new car).
