“ When nothing worked, he decided the least he could do was pick the yam bits out of his beard. But even the proved fruitless since the bits seemed to find their way into the deepest recesses of the beard, and the just small enough boy quickly grew squeamish. Judge if you must, but if you've ever had to pick yam bits out of an old man's bushy beard, I'm sure you'd forgive him. ”
