Mr. Whitewash, the polar bear gentleman, looked at Uncle Wigwag quite severely, but he said nothing, and only went on eating his breakfast.

“I think I know what made Uncle Wigwag laugh,” said Beckie Stubtail, the little girl bear, to Neddie, her brother, some time later.

“What?” he asked as he looked for his books to take to school. “What was it, Beckie?”

“He’s thinking of a joke to play,” said Beckie.

“I believe you’re right,” went on Neddie. “Oh, Beckie, and I’ve just thought of something, too.”

“What is it?” she asked as she looked to see if her doll, Sarah Janet Picklefeather, was nicely covered up in the puppy dog’s basket, so she wouldn’t get cold while Beckie was at school.

“We’ll just play a trick on Uncle Wigwag,” went on Neddie. “He plays so many on us that it’s about time we played one on him.”

“Oh, yes, let’s do it!” cried Beckie, clapping her little paws. “But it won’t be a mean or an unkind trick, will it, Neddie? For Uncle Wigwag is very good to us, and gives us lollypops, even if he does play a joke on us now and then.”

“Oh, no, it won’t be a bad trick,” said Neddie, laughing. “Only a funny one.”

So the two little bear children went on to school, talking on the way of the joke they would play on Uncle Wigwag. In fact, Neddie was thinking so much about this that he did not pay enough attention to his lessons, and when the teacher asked him: “Why does a cow eat grass?” Neddie answered: “Because it’s a joke!”
