I am going to try being better at posting some of the funny things S says, so here's a couple:
We're in the car and he's trying on Geoff's hard hat, he puts it on backwards and says,
"This is how cool kids wear their hats. Are you a cool adult?"
In preparation for my camping trip this year he had some good advice on keeping the bears away,
"You could try throwing a cookie at it." or
"You should go find the mama bear and tell her so she can tell the baby bear not to take your food."
