Burps and other bodily functions...

As we were tucking the boys into bed the other night, #3 (who makes us smell his breath after he brushes his teeth) asked us if he burped, would it ruin his toothpaste breath. I told him that it would depend on what he ate and how big of a burp it was, but that I thought the toothpaste smell would win out in the end.
#2 piped up with this comment.
#2: I'm glad burps don't smell as bad as toots because your mouth is a lot closer to your nose than your bum is.
Such a deep thinker.
