I know it's not about trees, nor is it so sweetly evocative and lyrical
as the two thus far presented, but in the spirit of the moment, and
continuing this collaborative attempt to get as far as humanly possible
from the topic in the subject line, here's a poem I wrote a few years
ago:

   Packet
   ~~~~~~~~~
   If the packet that's arriving at the designated port
   Isn't buffered pretty smartly in the stack
   You can only hope the protocol's got retries up its sleeve,
   Or the packet's getting dropped, and that's a fact. 

   Does the IP in the packet match the interface IP?
   Does the checksum in the header make good sense?
   Do the half a hundred RFCs that probably apply
   Unanimously speak in its defence?

   If so then quickly, quickly, pass the packet up the stack,
   There is application magic to be done!
   But if not, then give the packet the swift and silent flick
   And increment the error count by one.

Regards, K.
