Seinfeld is another show that I have only a marginal interest in, yet somehow I have ordered three different shirts for it. I guess the show is iconographic enough to appeal to my pop culture instinct. I have managed to avoid any shirts with Jerry on them. I think the supporting characters are better anyway.
Vandelay Industries is the fake company George often refers to as a possible employer or a company he owns. It is most notably known for selling latex products.
Vandelay Industries is also some kind of parent company. I guess the founders were huge Seinfeld fans or something, since none of them seem to be named Vandelay.
