A
knight that didn't quite make the cut in
Monty Python and the Holy Grail.
He was to have crossed the bridge in the following scene:
Bridgekeeper: Stop! Who would cross the Bridge of Death, yadda, yadda,
you know the rest.
Brian: Ask me the questions.
Bridgekeeper: What... is your name?
Brian: Sir Brian of Bell
Bridgekeeper: What... is your quest?
Brian: To code the one true operating system.
Bridgekeeper: What... are the only three lower case letters that are
not legal options to the unix command ls(1)?
Brian: BSD or System V?
Bridgekeeper: Umm... I don't... IEEE!
