Funny / Midnight Run

• Charles Grodin's performance throughout is awesome (it helped to get him out of a mid-career slump — he'd been doing things like The Great Muppet Caper) but a Crowning Moment is the kindly, slightly pedantic way that he corrects Jack's ex-wife's son when they meet:
  Kid: You don't look much like a criminal.
  Mardukas: I'm a white-collar criminal.
• Agent Mosely's increasing levels of pissed-offness every time he finds out that Jack has once more passed himself off as Agent Mosely.
  Train conductor: [referring to Jack] His real name was Mosely.
  Mosely: [Suddenly snapping] I'M MOSELY!
• "Eddie, I swear to God, don't fuckin' start with me right now, or I swear to God I'll shoot him in the head and dump him in a fuckin' swamp!" [Mardukas looks anxious; Walsh reassuringly shakes his head]
• The Running Gag with the sunglasses. In L.A., when Mosely and his underlings first meet Jack, it's by snatching him off the street and trying to intimidate him in the back seat of their car. He looks at each of them, then puts on his sunglasses to fit in. Mosely snatches them off Jack's face, then absently tosses them back when they leave. When Mosely and the FBI catch up with Jack and Mardukas in Chicago, Mosely taps Jack on the shoulder and asks "Remember me?" before putting on his sunglasses. Jack's response? "Agent Foster Grant!" After Jack gives the FBI the slip, he leaves his sunglasses perched on the steering wheel of their getaway car, telling a confused Mardukas that it's "an inside joke between me and Alonzo." Then in Arizona, after everything looks lost for Jack, he sits at the counter of a roadside diner to have a cup of coffee... and his sunglasses come sliding to him. He looks up to see Mosely and two dozen local cops surrounding him. Jack smiles, puts on the sunglasses, and says, "Gee! I've been looking all over for these. Thanks, Alonzo!"
• When it's revealed that Jack has stolen Mosely's FBI credentials, he initially mutters derisively to himself about Mosely's name being "Alonzo" and begins to walk off, and it seems like the scene is over... when suddenly Jack spins around posing dramatically with Alonzo's credentials in a "Freeze! I'm a G-Man!" style for no reason whatsoever.
• While on the flight to New York City, Jack pastes his picture onto Mosely's FBI badge, while the young boy sitting next to him looks on. Jack shows the finished job to the boy for approval, and the boy nods, as does Jack in an exaggerated way.
• Jack calls Eddie asking him to give him some money and threatens to kill Duke and dump him in a swamp if he doesn’t. He then quietly shakes his head to Duke to let him know that he’s not being serious.
• When Walsh discovers that Mardukas is trying to escape from him by personally piloting a plane, after having to forfeit an easy 5 hour flight back to LA earlier with him due to his supposed aerophobia. He even audaciously grins and waves goodbye at him as he taxis off!
  Walsh: (utterly incensed) "Fear of Flying", You son of a Bitch?!
