(Phone rings. Marge picks it up.)
Mysterious voice: Marge Simpson?
Marge: Who is this?
Frink: I'm an annonymous whistle-blower. I worked on a top-secret project called Operation HOYVIN-MAYVINGGG!
Marge: Professor Frink?
Frink: Oh, what gave me away? Out of curiosity, was it the hoyvin, or the mayvin, or was it the whole G'HOYVEY thing that I do?
