Two men are sitting in a bar drinking: one of them is a Joe Pesci Goodfellas-style dangerous gangster, and the other is a sardonic hipster type. So the Joe Pesci gangster guy sees a Geico ad on the bar TV set, and he nudges the hipster guy and says: “Hey, 15 minutes could save you 15% or more on car insurance!” And the hipster guy replies, contemptuously, without even bothering to look up from his glass of beer: “Yeah, everybody knows that…” Then the dangerous gangster guy says to the hipster guy, angrily: “What did you just (bleep)ing say to me, you little (bleep)? Do you think I’m (bleep)ing stupid or something, you (bleep)ing (bleep)? You’re (bleep)ing dead, mother(bleep)er!” And then the gangster whips out his gun and starts beating the hipster in the face with it, and the bartender (used to this sort of thing happening now and again) closes up the bar, after which he calls for some other gangsters to help get rid of the body. Then the announcer says: “Looks like someone could have used Geico life insurance! Call for a quote today!”
Then, as a tag, we see the gangster underlings loading the guy’s lifeless body into the trunk of their car, and as they close the trunk lid, we see it has a bumper sticker on it that reads: “I saved 15% (or more) with Geico!” (Or, as a special homage to Goodfellas, the guy’s body might not be completely lifeless after all; and after they close the trunk lid, we hear him banging on it trying to get out as they drive away.)
Here’s an example of the Geico ads I’m referring to here (although, as they say: “Everybody knows that!”):
