In the problem What Went Bad? from the book Get it Together:
The answer we got was pineapple upside-down cake. The only people that did not get sick were Alfie and Jason. Alfie ate every thing but the pineapple upside-down cake and the desert chicken. Jason ate the desert chicken. So the only thing it could have been bad was the pineapple upside down cake.
