BASEketball

Joe "Coop" Cooper and Doug Remer, two slackers and lifelong best friends, gate crash a high-school reunion and are shunned by their classmates. They find themselves outside drinking beer and shooting a basketball when two classmates challenge them to a game. After seeing that their opponents are very good at basketball, they say they will only play a game they picked up in the streets (while secretly inventing the rules as they play, based on both basketball and baseball). After winning, they decide to refine the rules to the game and Coop makes the first BASEketball out of a La-Z-Boy chair. Their friend, Kenny "Squeak" Scolari, tags along and the sport becomes very popular in the neighborhood over the next six months.
