Now I'm really confused. It looks like you want the sub-lists rearranged in 
some way, but it's not clear from the example what you want. I see the two 
lists that "match" (fat, skinny) are in 1st and 2nd place, and the two that 
match (hairy, bald) are in 3rd and 4th place. What do you wnat if there are 
more or less matches? Can you give us an algorithm instead of examples?
