I wouldn't say it's necessarily good. If you think of TV when a character says something as they're leaving a room and everyone goes "ooohhhh". That's a pithy comment. Something like:
"Hey baby, you looking for a real man for tonight?"
"Yeah, let me know if you see one!"
Good to be pithy when you're dealing with obnoxious drunks in a bar. Maybe not so much when talking with your boss.
