As tragic as yesterday’s postal shooting up near Santa Barbara is, a Seinfeld episode detailing it has already been done, just like it has for every other personal quirk and social occurrence over its run.

Season 4, episode 18, titled The Old Man
Originally aired: February 18, 1993
Writer: Bruce Kirschbaum; Story: Larry Charles

George Costanza: Let me ask you something... What do you do for a living, Newman?
Newman: I'm a United States postal worker.
George Costanza: Aren't those the guys that always go crazy and come back with a gun and shoot everybody?
Newman: Sometimes.
Jerry: Why is that?
Newman: Because the mail never stops. It just keeps coming and coming and coming. There's never a letup. It's relentless. Every day it piles up more and more, but the more you get out, the more it keeps coming. And then the bar code reader breaks. And then it's Publisher's Clearinghouse day.
Jerry: All right, all right.
