Quote from Roz in The Placeholder
Kenny: Oh, hi, guys. Hey, Doc! You're always free. My cousin's in town, why don't you help me show her the city? Frasier: Did Roz put you up to this? Roz: I had nothing to do with it, I swear to God. Frasier: Well, I'm sorry, Kenny, but I am booked all this weekend. Oh, here's luck. I found a perfectly good thimble in this pocket. See you later. [exits] Roz: Thanks anyway. Kenny: Hey, I tried.
