Quote from Carla in The Two Faces of Norm
Frasier: Where's Sam? Carla: He'll be right back. He just sold his Vette and he's picking up his new car. Cliff: Oh, yeah? What did he get? Turbo Z? Trans-Am? Carla: A Volare. Cliff: Oh, poor Sam. Carla: Yeah, he just called from the used car circus. It must have been the ringmaster's special. Anyway, he was really a little depressed about it, so maybe we just shouldn't mention it, all right? Cliff: Oh, yeah. Sam: [enters] Hi, guys. All: [sing] Volare, oh oh... Sam: Hey, listen, you got something to say to me, just say it. All: [sing] Cantare, oh oh oh oh
