2) Laugh as your friend's terminal goes audibly berserk, drawing the attention of everybody in the computer lab.

One time, I forgot to add the check to the queue, and I got aroused from my Friday hijinks with the alarming call that the Halon system had gone off and our operator wanted my blood. The printer had actually caught fire, due to 20,000 missing LF characters putting every single line on the same character (carriage return), burning a hole in the platen and yeah .. setting off the Halon.
That's when I learned, as a junior programmer, the value of pipes.
Sounds like a perfect BOFH episode.
The day I got my own pizzabox and ethernet connection, and thus didn't ever have to bother an Operator for access to anything, ever again, was another big step up in the career path I chose for myself .. still, I miss those grumpy old fuckers. They had good stories to tell, usually, and I still 'sync;sync;sync' to rewind tape, now and then, by muscle memory ..
