Cole has a snail in his.
One of his preschool teachers told him that if he picks his nose, a snail that lives there will bite his finger. I think it is a cute way to avoid spreading some preschool germs. Rob, however, is greatly disturbed.
When the snail came up in conversation the first time, Rob spent at least 30 minutes trying to convince Cole that his teacher was kidding.
He looked up Cole's nose and had Cole look up his to prove snails weren't there. Cole replied, "You can't see them. They're up really high."
Rob explained that there's nothing for a snail to eat there. Cole's rely was something along the lines of "Duh, it eats boogers."
Rob even resorted to "Who do you believe, your teacher or your daddy." The teacher won, much to Rob's dismay (I think homeschooling seriously crossed his mind).
In fact, Rob's attempts to dissuade have made Cole believe even more firmly. The snail is a regular topic of conversation now. Cole has determined that it lives in "the hard part" at the bridge of his nose; it doesn't mind sneezes, only fingers; and that everyone has a snail, even if he (i.e., daddy) doesn't believe it.
