New Fishing Pole


A boy rides the bus to the local Hardware Store. While there he buys a 
fishing pole that's 5 feet long. The boy goes to get on the bus to go home
but is stopped by the bus driver. The bus driver tells him he can't board 
the bus with anything over 4 feet long. 

The boy goes back to the Hardware store and buys one thing then returns 
and boards the bus. 

The pole can not be cut, bent, broken or taken apart. What did the boy buy 
to allow him to board the bus with the fishing pole?
