- The Great Gonzo: We all admire you for trying something so dangerous.
- Dr. Heathcliff 'Cliff' Huxtable: Dangerous? Waaaaaaaait a minute. Is the patient in trouble?
- The Great Gonzo: No, YOU are.
- The Great Gonzo: I thought I was in danger when I performed an appendectomy while being shot out of a cannon. Nothing compared to this.
- Dr. Heathcliff 'Cliff' Huxtable: [horrified; whispers] You're gonna shoot me out of a cannon?
- The Great Gonzo: No. You're going to be suspended upside down in a tank of water while playing "Lady of Spain" on the accordion.
