Some pearls from my Comp 101 professor in 1974:
"If it is easy, every SOB (edited for decorum) and his brother would be already doing it"
"You can't out-stink a skunk"
"Curse words are for the uneducated or unimaginative. It is far more creative to tell a fellow that he is the offspring of an unmarried female dog"
From my dad:
"Never take advise from someone who has nothing to lose if he is wrong"
From Alfred E. Neuman:
"If you kicked the person most directly responsible for all your problems,
you wouldn't be able to sit down for a week"
