15 things you didn't know about Caddyshack

Via Chris Lynch, this is pretty interesting.  For example:

13. The owners of the country club were not happy about the explosions on the golf course.

The climactic scene of Murray’s gopher-killing plastic explosives knocking in Danny’s putt to win the un-friendly wager between Al Czervik (Dangerfield) and Judge Smails (Knight) were real pyrotechnics set aflame at Rolling Hills. To pull off the effect, an artificial green was rigged with several incendiary packs and put into place between two fairways.

This was news to the owners of the country club, who had made it clear to filmmakers that the outrageous climax couldn't be shot anywhere near their golf course. To get them to “comply,” producer Jon Peters invited them out for a swanky lunch away from the country club to “thank them for letting the film use the location.” Ramis then had the special effects crew blow up the fake green while they were away. The fireball from the explosion was so large that a pilot landing a plane at nearby Fort Lauderdale-Hollywood International Airport radioed in to air traffic control that he thought he might have witnessed a crash. 

The others are as good.
