Almost every April Fools' Day (1 April) since 1989, the Internet Engineering Task Force has published one or more humorous RFC documents, following in the path blazed by the June 1973 RFC 527 entitled ARPAWOCKY, which parodied Lewis Carroll's nonsense poem Jabberwocky. The following list also includes humorous RFCs published on other dates.
