In the movie Jerry Maguire (1996), Tom Cruise plays the eponymous role, a sports agent. He comes up with an idea to create a "mission statement" for his company on "what we think but don't say," so he composes this, prints out multiple copies, and puts these copies in mailboxes for people that he works with at a hotel where they are staying. (This idea actually becomes his undoing; he is fired from the company shortly after.)According to tvtropes.com, after distributing copies of his statement, Maguire suddenly has a big flash that this is not a good idea because he sees some scenes from Hawaii Five-O on TV (I don't follow the logic of this). ("The morning after Jerry sends out his mission statement to everyone in his company that's at the hotel, he's drying off after showering, and an episode of Hawaii Five-O is on, which makes him have a 'My God, What Have I Done?' moment, and he calls the desk to try and stop delivery of those mission statements, but he's too late.")
In his hotel room, Maguire is watching TV and you hear and then see Jack Lord on TV as McGarrett is saying, "There are dangerous animals in the world and some of them walk on two feet. They don't want peace and they're not capable of love. Society, and that means you and you and you [the original has one more "and you"] need protection from these warped minds."
This comes from the first season episode S01E21, Not That Much Different, where McGarrett is giving radical newspaper staff members a big speech.
Presumably following this excerpt immediately, the clip in the film then switches to scenes from the fifth season Five-O episode, S05E12 The Clock Struck Twelve, where cops are planting phony bombs in the Honolulu Judiciary Building which is going to have a trial for radicals accused of serious crimes, to show how bad the security for the place is.
We see someone drop a bowling ball bag on the ground; in this show as broadcast, a cop takes a "bomb" out of this bag and puts it in an ashtray. There are a couple of scenes from the broadcast omitted, and the clip in the movie ends with a closeup of a clock connected to a phony bomb rolling over from 11:59 to 12:00 noon and the camera focusing on McGarrett, who says "Boom."
