...Wait, what?! One of the best April Fool's jokes ever was played by Representative Tom Moore of Waco, Texas. Apparently there was a history of Texas representatives not reading or fully understanding the bills they were passing, and Moore wanted to point that out. On April 1, 1971, Moore presented a resolution commending Albert DeSalvo for "his unselfish service to his county, his state and his community."
For those who don't recall, DeSalvo was known as The Boston Strangler, and was responsible for the murders of at least thirteen women in the early 1960s. Obviously, Moore was hoping to grab his fellow reps attention, but as it turned out, the resolution was passed unanimously, at which point he withdrew it and explained. (Some think that his fellow representatives were paying attention, got the joke, and returned it to him in kind.)
