NACK, NACK.
Who's there?
ATM.
ATM who?
NACK, NACK.
"NACK" is a "negative acknowledgement", a very old communications protocol for "I don't understand". NACK usually forces a resynchronization or renegotiation between end points. ATM is "Asynchronous Transfer Mode"; a couple of decades ago it was a relatively high-speed packet technology that lost out to other technologies. - via <http://stackoverflow.com/a/1590009/773209>

The TCP joke is a personal favourite:
"Hi, I'd like to hear a TCP joke."
"Hello, would you like to hear a TCP joke?"
"Yes, I'd like to hear a TCP joke."
"OK, I'll tell you a TCP joke."
"Ok, I will hear a TCP joke."
"Are you ready to hear a TCP joke?"
"Yes, I am ready to hear a TCP joke."
"Ok, I am about to send the TCP joke. It will last 10 seconds, it has two characters, it does not have a setting, it ends with a punchline."
"Ok, I am ready to get your TCP joke that will last 10 seconds, has two characters, does not have an explicit setting, and ends with a punchline."
"I'm sorry, your connection has timed out. Hello, would you like to hear a TCP joke?"
With thanks to Scott Sullivan who told me this one, I think it's a great follow-up to the TCP joke: "I'd tell you a UDP joke but you might not get it." Which also says a lot about the difference between the two protocols ... -- Giles http://www.gilesorr.com/ gilesorr@gmail.com
