Though entertaining enough, this play appears in its entirety as a small part of Sorrentino's magnum opus MULLIGAN STEW. You can read it as easily there as in this form. Plus you'll have the rest of Mulligan Stew as well. So I recommend you only buy this volume if you're the sort of collector who owns books because of what they are, not what they say.
A fungo bat is used by the coach to hit ground balls or fly balls to his team. All throughout high school and college many players use fungo bats to play fungo golf. This is when each person has a fungo bat and a baseball and they pick out targets around their field or complex and basically play it in the same manner as golf. Fungo bats should not be used to hit a pitched baseball because they are much weaker than normal bats and will break much much easier.
Fungo golf is a game involving two or more players in which they use fungo bats and baseballs and their object is to hit certain objects at a field. Fungo golf is played very similar to golf, where the player with the fewest strokes after a certain number of holes (typically nine or eighteen) wins the game. While there is no concrete history of how fungo golf was created, it has spread throughout America as a popular game especially with baseball players and coaches.
