Meta Monday: Comedic/Dramatic Socipathy

What is something you've seen or read that worked for the plot, but would be perceived as dangerous, obnoxious or even evil in the real world? Did it work for you because it was fiction, or did it still bother you?

(Let's assume the characters doing said thing were supposed to be at least marginally likable.)

Example: Joey causes a two hour traffic delay while proposing to his girlfriend in the middle of an intersection. (Actually, this happened IRL.) We see two ambulances being among the stuck vehicles.
