At the moment, Adam's sole aim in life is to incorporate words like 'butt', 'fart', 'underpants', 'poop' etc into as many sentences as he can. And then to laugh hysterically once he has done so.
I give you two examples of Adam's latest jokes:
YOU SAID UNDERPANTS!!! HAHAHAHAHA!!
Why did the chicken cross the road?
I have no idea why the chicken crossed the road, Adam, but I am sure you will tell me
To get his BUTT to the other side! HAHAHAHAHA!!!
Seriously, (almost) 7 year old boys are extremely childish.
(Which is only slightly better than Kate's description of Adam as "Handsome, but stupid")
