Step 1. Download ‘Cyrano de Bergerac’. (Optional: just go watch [*Roxanne*](http://en.wikipedia.org/wiki/Roxanne_(film)).
Step 2: Change the names to Worf, Quark and Grilka.
There is (apparently) no step 3.
I’m being a bit unfair. Despite the fears I expressed only a few episodes ago, the inevitable Klingon/Ferengi episode turned out OK. That was because by putting Worf into the Cyrano role we get to see some interesting reactions from him, and it serves well to finally bring the Dax/Worf romance to fruition. And the tone manages to hit romantic comedy – rare for a show that is not very good at tone changes.
