Things aren''t going well for John McClane: his marriage is breaking up, he''s been suspended from the force and now the brother of Hans Gruber, the German terrorist he threw off a building a few years back, is threatening to blow up a school if McClane doesn''t run around the city solving his demeaning and dangerous puzzles. With the help of Zeus, a Harlem electrician, McClane discovers Gruber''s plot to distract the NYPD while he clears the federal bank of billions of dollars of gold.

Zeus: Woah! Is that a bomb?
John: Yeah. Go ahead and grab it!
Zeus: No. You''re the cop!
John: Well, Simon says you''re supposed to be helpin'' with this!
Zeus: I''m helpin''.
John: Well, when are you gonna start helpin''?
Zus: After you get the bomb.
Zeus: Careful.
John: I''m bein'' careful!
Zus: Don''t open.
John: What? I gotta open it. It''s gonna be all right.
Zeus: Shit! I told you not to open it!
Simon: I trust you see the message? It has a proximity circuit（无线电引爆电路）. So, please don''t run.
John: Yeah, I got it. We''re not gonna run.How do we turn this thing off?
Simon: On the fountain there should be two jugs. Do you see them? A five gallon jug and a three gallon jug. Fill one of the jug with exactly four gallons of water... and place it on the scale and the time will stop. You must be precise. One ounce more or less will result in detonation（炸弹引爆）. If you''re still alive in five minutes, we''ll speak again.
John: Wait! Wait a sec.!
John: I don''t get it. Do you get it?
Zeus: No.
John: Get the jugs.
John: Obviously we can''t fill the 3 gallon jug with four gallons of water, right?
Zeus: Obviously.
John: All right, I know. Here we go. We fill the three gallon jug exactly to the top, right? OK, now we pour that three gallons into the 5 gallon jug. Giving us exactly three gallons in the 5 gallon jug. Right?
Zeus: Right, then what?
John: OK, now we take the 3 gallon jug and fill that a third of the way up.
Zeus: No, No. No. He said "Be precise". Exactly four gallons.
John: Every cop in fifty miles is runnin'' his ass off, and I''m out here playing kids'' games in the park!
Zeus: Hey! You wanna focus on the problem at hand?
