I just rode a fairly hilly Century with a guy who, shortly after he commented about how much faster than he I was at climbing, proudly announced that he had done the entire ride in the big ring.
When asked why, he replied that he liked the challenge.
Strangely, that cross chaining SOB did not understand my actual face-palm. I'll save my chain, cassette and knees for better things and go faster to boot, thank you very much.
