I believe you are correct vrooomed. The other day I noticed Darren Drozdov listed under football (as he was a former football player) but his wrestling cards were listed too (some could say more people know him as Droz than as the football player).
As for Farrah Fawcett, it could be possible she was included in a baseball set and it was her first listed card, so she is placed in baseball. It should be moved I guess, but aside from searching I'm not sure if it makes that big of a difference.

In the process of updating my collection so don't trust any of my lists right now.
