- Dr. Raymond Stantz: Don't worry, Mr. Metzenbaum, we'll have those Valkyries out of here before you can say "Nibelungenlied", twice.

- Dr. Egon Spengler: This is the opera, Peter, you can't put a price tag on art. It's an honor to serve art. On behalf of the Ghostbusters, I'd like to volunteer our services, free of charge.
- Dr. Peter Venkman: [grabs Egon's shoulders] What? F-f-f-free? I can't even say it!
