Fresh air

Boy this weekend was great, wasn't it? I was playing with the kids in the backyard:

Max: Daddy, push me really high on the swing.
G-man: Ok, but don't fall off.
Max: Doesn't it smell really good out here?
G-man: Yeah, really good. Smells kinda fresh, don't ya think?
Max: Yeah, fresh and good.
G-man: Almost as good as my own farts.
Max, grabbing the chain: Ok, you can stop pushing me now.
