Al and WCs

Al wrote on his blog about an epigram he saw written on the wall of a WC. It said "information is not knowledge". From the epigram, somebody drew an arrow that pointed to the sentence "thanks for the information". I think it's the best piece of WC philosophy I have ever heard about. (by the way, today al and I got into the WC to pee (separate restrooms, don't worry choche), and I asked him whether he saw the sentence on the same WC we were at, but he said it was somewhere else, I don't exactly remember where. it was sort of comic)
