I recall a comic strip about the statement that your clothes make, but don't seem to be able to find it. It goes something like this:
Cartoon of a Guy with great hair, smile, and a suit.
Caption: "I'm going places so I won't be here long enough to learn your name".
Cartoon of a Guy in a dirty t-shirt (note mustard stain) and flip flops.
Caption: "I'm the only one who understands the unix system. Worship me".
There were more panels in between but I don't remember them. I think it's a Dilbert strip.
