From mail:

I noticed a bug in the Jack Attack. The category I forget was something about amputee jokes; I was able to guess correctly and incorrectly, but there were 2 matches in this set where clicking the correct match on screen registered as incorrect -- I am pretty sure they are correct, though. The matches were (clue: answer) --

Torso on the wall: Art
Torso in the pool: Bob

They came by twice and each time when I chose the answer it registered as incorrect.
