Bat stretcher

A bat stretcher is an essential piece of baseball equipment. New batboys are often sent to search the stadium in search for a "left-handed bat stretcher". After a lengthy search, the poor young man is informed that there is no such tool as a bat stretcher, much to the amusement of those in on the joke.

The bat stretcher joke appears in Bat Boy. My True Life Adventures Coming of Age with the New York Yankees, written by Matthew McGough. It was featured on the short lived drama Clubhouse when the batboy, Pete, was sent to find one.
