These guys have an amazing sense of humor. Vint Cerf himself keeps making hilarious RFCs, for instance:

"Twas the Night Before Start-up" [http://tools.ietf.org/html/rfc968] that ends with:

      At last he was finished and wearily sighed
      and turned to explain why the system had died.
      I twisted my fingers and counted to ten;
      an off-by-one index had done it again...

and "A VIEW FROM THE 21ST CENTURY" [http://tools.ietf.org/html/rfc1607] that talks about the letters discovered in September 1993 in a reverse time-capsule apparently sent from 2023.

My favorite is one by S. Christie about implementing The Infinite Monkey Protocol Suite (IMPS) [http://tools.ietf.org/html/rfc2795].
