The 25 Most Insane Protester Signs.
(Probably not worksafe.) Some of them are sarcastic; my favourite is the one with a rainbow flag in one hand and a sign declaring that all computers should be destroyed because Alan Turing was gay in the other, the sign clearly having been made on a computer. At least I hope that one was sarcastic. On the other hand, "Who Needs Oil? I Ride The Bus" appears to be serious.
