Farts

I was driving my 12 year old son home from school with the poodle in the car and I asked him if he had farted. He told me no and blamed the dog. We wound down the windows and the farting discussion continued along these llines -
Son: You can really tell a Casey fart (one of his friends).
Me: How?
Son: It is just easy to tell, but you have to have a good nose and good eyes to detect a fart at school.
Me: Why would you need good eyes?
Son: You can see their pants wobble.
I laughed so hard. What is it with boys and fart talk?
