"You can't fix stupid."
Or,
"Stupid is, as stupid does."
Or,
"You can lead a horse to water, but you can't force it to drink it."
Or,
"You might as well mind your own business!!"
Once, I was with a friend of mine (a recent convert) at the bar, and this chick (a friend of his) approached him,
with a lit cigarette in her fingers, and stated "You would be better off with a cigarette, because no-one knows what's in those things"
My friend just pulled a bottle from his pocket, read the list of 6 or so ingredients, and asked her if she could name all thousands of chemicals in the smoke of her cigarette. By then, I just
had to chime in the conversation...
Being my obnoxious self, I simply said aloud: "That may be too much to ask your friend, David... maybe she could name just the 60 or so carcinogenics..."
That ended the conversation mighty fast...!
