Lieutenant Frank Drebin's (Leslie Nielsen's) line about shooting the Shakespeare in the Park performers is a close parody of a line Inspector "Dirty" Harry Callahan (Clint Eastwood) said about shooting a rapist in Dirty Harry (1971).
So they were able to get him to the hospital in time?
Frank: Yes, he's in the intensive care ward at Our Lady of the Worthless Miracle.
When Frank Drebin is umpiring the baseball game, a scene shows four Angels players crossing second base during the same play. This is a joke, as the situation is impossible in baseball; even during a grand slam, only three players touch second base. The scoreboard later shows no more than 2 runs scoring in any inning, in keeping with the joke.
"Mr. Weiss' Divorce Attorney.................. MARSHA DURKO"
When aired on Comedy Central, Frank's line "Nice beaver" was changed to "Nice one", ruining the joke.
