Peanut butter and banana?

I'm really having a hard time understanding this. What started as a seemingly good idea morphed into something so wrong. We chose two sixth grade classes to teach a special lesson; how to make a peanut butter and banana sandwich using English. The error occurred when the students opted to bring additional items to the class. Some groups ended up with such a schmorgasborg of ingredients, I couldn't initially imagine what the potential was. In the end, though some groups did successfully manufacture peanut butter and banana sandwiches, some groups ended up with sandwiches sans peanut butter AND banana. Worse though, were the groups which failed to fully transform, and ended up with Spam, cheese, ketchup, and banana sandwiches.
