A boy goes and buys a one-piece fishing pole that is 6' 3" long. As he goes to get on the bus, the bus driver tells him that he can't take anything on the bus longer than 6'.
The boy goes back to town, buys one more thing, and the bus driver allows him on the bus.
He did not damage the fishing pole in any way.
What did he buy, and what did he do with it?
...he could have bought some fishing line. Thread it up through the eyes of the rod and create a loop of line along its length that extends back down to the handle again. Most fishing rods are designed to bend to some extent, so by keeping the loop of line held taut, and the rod bent over, it could be considered shorter now as a result.
