My young son, who has sat through numerous evenings of "American Idol" with his sisters, knows about contestants. Due to some digestive issues with some of his family members, he also knows about intestines.

This afternoon a gnat flew into his eye. "Is there something called an 'Eye Bug'? Because a bug just flew in my eye. Is there such a thing as an Eye Bug?"

"Oh," I answered, "those are probably gnats. They fly into your eye, but you can gently wipe them away out the corner of your eye."

"They fly into your eye?"

"Well, not inside it."

"Can they get inside and see your contestines?"

"They--" I had to stop and chuckle. "I'm sorry, I just, you said, well, they can't get inside through your eye, no, and they can't see your intestines."

"Oh. Well, this fly is in my eye right now."

"The gnat?"

"The fly."

We got it out. It never saw his contestines.
