I aspire to be able to be as seriously silly as an RFC author on April First. Seldom does a joke have such well-researched due diligence.

One of the best IMHO: IP over Avian Carrier

Real-life implementation

On 28 April 2001, IPoAC was actually implemented by the Bergen Linux user group, under the name CPIP (for "Carrier Pigeon Internet Protocol").

[4] They sent nine packets over a distance of approximately five kilometers (three miles), each carried by an individual pigeon and containing one ping (ICMP Echo Request), and received four responses.

55% packet loss!!

My favorite novelty RFC is still the first. RFC 527, ARPAWOCKY:

https://tools.ietf.org/html/rfc527

The archaic jargon and playful imagery harken back to the culture and experience of a time before the Internet even had it's name. Or maybe I romanticize too much :).
