One of my co-workers just announced something kind of positive (I can't even remember what now) and one of the other ones followed it up with, "Now we do the dance of joy!".
They all laughed, but in the ensuing conversation about where that expression came from, none of them could remember that it was from the long-passed ABC show Perfect Strangers. I confess that I knew where the expression came from, but I was too embarrassed to say anything, perhaps outing myself as a one-time TGIF viewer.
