If your youngest son, while happily sucking on his toes, suddenly lets loose with a thunderous fart, do you:

1. Point a finger and loudly claim, "It was him!"

2. Assume there's some sort of call and response thing going on and answer.

3. Beam proudly and say, "That's my boy!"

Ha. Trick question. It turns out that none of these is the right answer. At least, not according to Joanne.
