* You know the line:
--> '''Sonny''': Is there any special country you want to go to?\\
'''Sal''': [''pause''] Wyoming.\\
'''Sonny''': ...No Wyoming. That's not a country.
** Cazale ad-libbed "Wyoming", making Lumet laugh so loud the director worried the take was ruined. Thankfully, it wasn't.
* The crowd's reaction to Sonny patting down the doctor and agent he allows inside the bank for weapons, after word gets out that he's bisexual.
* Sal's [[FlatWhat expression]] upon hearing the TV announce that [[MistakenForGay "two homosexuals are robbing the bank."]]
* Sonny answering the phone in the bank:
-->"WNEW, plays all the hits."
* "Attica! Attica!" Come on, it's just ''funny''. The crowd's reaction seals it.
* Sonny's exasperation over the third robber wanting to leave right after the robbery starts, and then having to remind him to leave the car keys.
* When he learns that Leon is Sonny's "wife," Moretti's [[FlatWhat expression]] and his [[ImpliedFacepalm exasperated]] [[YouHaveGotToBeKiddingMe muttering, "Jesus Christ,"]] are priceless. Considering how crazy the situation has been, you just ''know'' he's thinking, "Should've seen ''that'' coming!"
* After [[spoiler:the bank manager goes into diabetic shock]], Sonny calls for a doctor. When the police find a doctor and he comes running up, the crowd [[{{Troll}} eggs him on, shouting, "Hup! Hup! Hup! Hup! Hup!"]]
