I work with a guy who is a bit of a moron. He's also shown me countless times over the years that he doesn't know how to use the word "than" in a sentence.
I just sent him the following email in a response to an email regarding a project he's working on and he wanted my input on his plan:
"I'd prefer you to be safe than sorry, but you're so frequently safe then sorry that it probably doesn't make a difference how safe you try to be."
Yes, I'm happy with myself for being both insulting and confusing to the poor guy.
