I have a habit of saying "good times" when things aren't going so well but can't be helped. When it's bad or weird and the only thing left is to work through it, I'll say, "good times" and start working.
Yesterday I happened to say it in front of someone I barely knew. His response: "I don't think this is good."
That kind of laugh was enough to last me all day, after I explained "good times" to him!
