"We never tried to use funny clothing. Of course, there were times when we would wear odd garments for a special humorous effect, but as far as our two characters were concerned, we never tried to get very far from what was real. We always wore a stand-up collar but there wasn't anything unreal about them, especially in the twenties and early thirties. Stand-up collars were formal and slightly different, but never too obviously so. They gave us, together with our derbies, a something we felt these characters needed—a kind of phony dignity. There's nothing funnier than a guy being dignified and dumb. [...] The derby hat to me has always seemed part of a comic's make-up for as far back as I can remember. I'm sure that's why Charlie wore one. Most of the comics we saw as boys wore them, so I guess you'd say that's one item that's strictly in the public domain."
