Max's underballs

We were headed to the State Fair on Friday for Bryn's birthday and I asked Max if he wanted to wear pants or shorts to the fair.
He said, "Shorts, no wait, my underballs."
I replied, "What?"
"My underballs."
"Your underballs?"
"Yeah."
"Oh, you mean your overalls?"
Yes, he did, in fact mean his overalls, but that was about the funniest thing I've ever heard come out of that kids mouth. The other funny thing is that he knew overalls were appropriate attire for the fair. i really wish i had a picture of him wearing them, cuz they're a couple inches too short and very Opie.
