Since it seems to be the geek humour week at this blog, let’s recover something I discovered some time ago. It’s a web site which describe itself in this fashion:

Approximately 31 RFCs so far, starting with RFC 527, need some additional attention. Most of them were released on the 1st of April, claiming to be “funny”, for some reason in some cultures. This Document represents the current state of research to define the algorithm “IS_RFC_FUNNY” which identifies such RFC’s.

I’d bet the most known of those is RFC 1149 “Standard for the transmission of IP datagrams on avian carriers.”, but there are really good ones there.

• RFC 2549: IP over Avian Carriers with Quality of Service.
• RFC 2795: The Infinite Monkey Protocol Suite (IMPS).
• RFC 3251: Electricity over IP.

And to escape for our computer geeky humour to something more generic: Top 100 April Fool’s Day Hoaxes. I’ve found specially interesting #5: that’s what happens when you let typography geeks write a joke.

UPDATE: C. Ovidiu points me to another funny one, RFC 3514: The Security Flag in the IPv4 Header
