I was helping a friend with some IP Suite confusion, so I wrote a little story: UDP: "TCP you're such a control freak and you're always kissing ass Ack Ack Ack that's all you ever do" TCP replies: "UDP, we're spoken about this before. I am a part of something greater than you. You can sit here on the couch and be unreliable, connectionless you have no sequence or order and HEY HEY, ARE YOU LISTENING TO ME WHEN I TALK TO YOU? __ACKNOWLEDGE ME!_" UDP begins to cry and talk to his teddy bear. "he's not the boss of me" TCP interrupts and say "UDP, I am your FATHER". UDP just stares off into space, doesn't acknowledge TCP and after several retries, TCP moves on.
