Not sure about a joke using the foobinacci sequence but there are fibonacci numbers too. So 11 should be a foobinacci number, the number of suits required from a tailor before you can know if he's good or not.
When I read Foo's initial post, I thought I had similar sentiments but from his later posts, maybe not. For me, it is that the forums are filled with affiliate vendor threads with hundreds of posts but nearly all of which essentially consists of a circlejerk saying "Yaay!!" in response to a vendor saying "Here is a great new product I am selling you!" For me, I have no problem with people like David, which I guess is where I differ with Foo.
I do like the colors of the sweats and tees in the PBJ line. Not going to buy it because it's Uniqlo though. If I bought a deep indigo dyed shirt from somewhere else and washed it a bunch of times, is that what it'll end up looking like? I'm guessing that's how Uniqlo did it but I'm not sure.
