What do little girls who can't dig for worms at recess do for kicks?
They put snails up their noses.
And if they're REALLY lucky, one will get stuck in someone's adorable little nostril. And if they are even LUCKIER, the only girl in the class who can't speak English is elected to go and try to tell the teacher - using hand motions and a modified version of Chinese and English.
This works out well for the snail sniffing lass, however, because in the length of time it took to shock the teacher into action, the nose had sufficiently "run" enough to expel said snail.
Some lessons are best learned with no assistance.
