"Didn't say I did. Chub challenged me to give a better one, and I did it."
"Here's one," said Roy. "I think it's original, but I won't vouch for it. When is a wagon not a wagon?"
"When it’s a cart?" asked the doctor.
"No, sir."
"When it's awheel," cried Harry, eagerly.
"N-no, but that isn't so bad. Give it up?"
"Yes."
"When it turns into a road."
"That's lovely!" said Harry. "I must remember that. 'When is a wagon not a wagon? When it's a road;' no, no, 'when it turns into a road.' I know one, but it's not original."
"Out with it," said Chub. "The answer's on the tip of my tongue."
"Well, then, what's the best age for a small house?"
"Cott-age," answered Dick, to Harry's disappointment.
"You knew it," she objected. "You ought to have let Chub try."
