From Seinfeld's AMA today:
What is the most mundane thing you and Larry [David] have obsessed over?
We never obsess over anything that isn't mundane. Most recent was intentional mumbling. We wrote this script for this thing that you will eventually see but I can't reveal what it is at this time. All I can do is tell you is that it's big, huge, gigantic. Even bigger than that Amazon package.(He's referring to this package.) (It was a car.)
