One of These Things is Not Like the Others

You remember the old song from Sesame Street, right? One of these things is not like the others; one of these things does not belong. Not that I think about it, I don't remember if there is more to that song or not. Either way, the SA Goons have decided to educate and confound you with wacky foursomes where there is always an odd man out. Which odd man really depends on how nit-picky you are, so have fun and talk about what you find with your friends.
