Mike is proud of this spikey hair. Small for his age, his spikes
make him look taller and very grown up. To his horror, he discovers
he has head lice. The great hat parade is only two days away and he
longs to win a prize for best hat. But how can he, when he can't
stop scratching long enough to make one?
