I'm pretty sure @Kurtis Wolfe will appreciate the joke about the TCP packet:
4. A TCP packet walks into a bar, and says to the barman: “Hello, I’d like a beer.” The barman replies: “Hello, you’d like a beer?” “Yes,” replies the TCP packet, “I’d like a beer.”
(Unhappy news - Bob Braden, inventor of the TCP protocol passed away 5 months ago ... I had the pleasure of working with him on a joint project between my major west coast university and ISI).
