What are little boys made of?

Why do little boys, or just boys in general for that matter, think that it is so funny when they let one rip? I'm in the middle of changing Dillon's diaper a bit ago and lift up his legs to get the diaper under him. Wrong move, mom! Obviously my reaction was none too pleasant as I ask "What in the world have you been eating, kid?" My son, on the other hand, thought this was the funniest thing since Bush expressed his concern over the OB-GYNs not being able to practice their love with women across the country. Excuse me, what did he just say? I will have to say, though, all was forgiven when he squealed with delight about getting to lay in the bed with mommy to cuddle up. What a cutie! I love this little guy so much :)
