Letter sounds

Turner came up to me and asked me what letter makes the "puh puh puh" sound. Well like any good mother with a four year old little boy does, I dutifully answered the question like I do the other 6,000 times a day I am asked a question. Well, when I answered P, Max and Turner started CrAcKiNg uP! I had been set up! What is it with little boys and the words pee and poo??? But I must admit I was a tad impressed with the set up!
