Musical
Amos immediately telling the police the truth when he realizes that the "burglar" was the man who sold them furniture. He then delivers a "The Reason You Suck" Speech to Roxie for cheating on him, murdering her lover, and lying to him about it.
Also, at the end, Amos leaves Roxie when she tells him she lied about being pregnant. It may not seem like much, considering Amos is left with his day job, but he is finally tired of her scheming and manipulating and cuts her loose. Roxie soon realizes she's doomed to obscurity as the crowds leave.
Film
One for Amos in the film. When Roxie tries calling him out and calling him a "disloyal husband," he gives her a Death Glare and walks away from her in disgust.
One neighbor sees Roxie with Fred, who lies that Fred is her "brother". She gives testimony to the police that she's seen Fred "jazzing" with Roxie for three months, and identifies his body with an Everyone Has Standards expression.
The cops, in general, are on the ball when it comes to apprehending murderers. They appear along with a detective mere minutes after Velma murders her sister and husband, despite her attempts to hide the gun and evidence. Later, when questioning Amos, they immediately arrest Roxie when she angrily confesses to the murder.
The staging of "They Both Reached for the Gun," where Roxie is Billy's dummy, and the press are marionettes. The makeup, the choreography, interspersed with random cuts to the real-world press conference. By the end of it, Roxie has made the headlines.
Billy's Batman Gambit to get Velma and Roxie off. He has Velma cut a plea deal, uses a fake version of Roxie's diary as a bargaining chip, and discredits the prosecutor. And if you listen closely, he never actually lies during his tap-dance.
A small but no less impressive one comes near the end of "All That Jazz". Velma's just killed her husband and sister, and done a showstopping rendition of the song she was supposed to do with her sister. Near the end of it, the cops come in, and she sees them. Does she run off stage? Nope. She gives them a very bold "Come and get me" look, complete with a foot stamp, and finishes the song, completely bringing the house down in the process.
"No, I'm no one's wife but oh, I love my life and all...that...jazz!" Not only did she confess to the police and the public at large (she's no one's wife because she just killed him), on stage, in song, she admits she doesn't feel the least remorse.
The entirety of the "Cell Block Tango" especially the film version.

Doubles as a Heartwarming Moment as after the final strike the entire stadium sang in unison the famous "Go Cubs Go!" song.
108 years after their last World Series Win, the Chicago Cubs manage to win the 2016 World Series in the 7th Game against the Cleveland Indians by a single run, coming back from an 8th Inning Tie in a tense, 10 inning game, breaking the dread Curse of the Billy Goat.
