A random professor once walked in the room and my friend asked him to explain UDP vs. TCP.
He grabs all the dry erase markers from the board, and this happened:
Prof: "Would you like a marker?"
Student: "ok"
[prof tosses him a marker]
Prof: "Did you get the marker"
Student: "Yes"
[repeat until all markers are transmitted and acknowledged]
Then the professor takes the markers back and says "and this is how UDP works!" and throws all the markers at once, without warning, and my friend catches zero of them.
I never forgot TCP vs. UDP from then on. And I wasn't even remotely a compoooter major at the time*
*but it was a physical computing/Arduino class, which 100% set me on the path that I am on now...
