Frank says:

I'd like to know who's Plunkin' the monkeys? -- It was on the Tonight Show with Johnny Carson. I can't remember the year maybe 10 years ago? They were talking about AIDS and how AIDS all got started, he had 3 theory's. First Frank said something about AIDS being a government test gone wrong Then maybe it was an Alien (ET) test or mistake and finally they talked about the theory of AIDS coming from a monkey and then Frank said " I'd like to know who's plunkin' the monkey's?"
