Quote from Morty Seinfeld in The Raincoats
Kramer: So how did you come up with the idea for the belt-less trench coat? Morty Seinfeld: I came home one night, and I tripped over one of Jerry's toys. So I took out my belt just to threaten him, and I got a glimpse of myself in the mirror. Kramer: How serendipitous. Morty Seinfeld: So that night, I cut off the loops and the Executive was born. Kramer: Mmm. Jerry: He also came up with an idea for a brimless rain-hat but that never materialized.
