Tom and O'Holleran took a walk through the suburbs, and came upon some blackberry bushes laden with half-ripe fruit.
"I say," says O'Holleran, "what kind of bushes do you call those, Tom?"
"Whoi, you fule," says Tom, "they're blackberries."
"Get out," says O'Holleran, "they're red."
"Sure," says Tom, "but every fule knows that blackberries are always red when they're green."
A little way beyond, they came to a crossroad. Tom said they ought to go to the right and O'Holleran said to the left.
They argued for a while, and Tom says:
"I'll tell you what we'll do. You go by one and I'll take the other. If I get home first, I'll put a chalk mark on the door, and if you get there first you rub it out."
