As some of you may remember....I have had a little trouble with Nick always picking his nose. It started shortly after we enrolled him into daycare. When I would ask him to quit he would giggle thinking it was a joke. Now I can say, "Thank you Shel Silverstein for letting my child know why he should not dig for gold!"
Warning
Inside everybody's nose
There lives a sharp-toothed snail.
So if you stick your finger in,
He may bite off your nail.
Stick it farther up inside,
And he may bite your ring off.
Stick it all the way, and he
May bite the whole darn thing off.
Shel Silverstien
