Character mistake: When Frank proposes to a hypnotised Jane at the ball game, he says he bought the engagement ring 'this morning.' That morning they were still broken up, with Frank suspecting Jane of setting him up to be shot. They didn't reconcile until immediately before the game.

Factual error: At the onset of the baseball game, take a look at the Angel's catcher as Mariner Jay Johnstone steps up to bat. You will see he is wearing just a standard baseball hat under his catcher's helmet. MLB rules requires some form of certified (protective inside and out) plastic helmet for catchers, and thus this would not be allowed. (01:07:35)
Driving instructor: Now, Stephanie, gently extend your arm. Extend your middle finger.
Question: What is the name of the song playing during the main credits?
Answer: The opening song during the credits is the theme song from the 1982 TV series "Police Squad!" The Naked Gun movies are based on the short lived TV series.





Chosen answer: "I'm Into Something Good." It's the second song listed in the music credits, and if you don't read all the credits you miss a good part of the gags in the movie.
"I'm Into Something Good" is played during the scenes where Frank is going out with Jane. The song the person is asking about is this song. Https://www.youtube.com/watch?v=wn-MlISDsNs.
