Episode at unemployment office. George dates the daughter of the clerk. Notice the daughter's sweater. It is the same one worn in the �sniffing accountant� by Kramer?
I think that George was obsessed by sweaters. He is featured in many sweater references.
He buys a defective sweater for Elaine. Then gives it to the office cleaner. And then it is thrown in his face.
Then we get the sweater that is ruined by the �baby shower woman�.
And the sweater George wears in �The Outing�. He makes a point to show it off.
George likes sweaters. Burly guys need sweaters.
