From RFC 1149 - Standard for the transmission of IP datagrams on avian 
carriers
http://www.faqs.org/rfcs/rfc1149.html

"...Frame Format The IP datagram is printed, on a small scroll of paper, in 
hexadecimal, with each octet separated by whitestuff and blackstuff. The 
scroll of paper is wrapped around one leg of the avian carrier. A band of 
duct tape is used to secure the datagram's edges. The bandwidth is limited 
to the leg length. The MTU is variable, and paradoxically, generally 
increases with increased carrier age. A typical MTU is 256 milligrams. 
Some datagram padding may be needed.

Thought for the day:
    The only thing that hurts more than paying income tax
    is not having to pay income tax.
