General Jack D. Ripper: Mandrake. Mandrake, have you never wondered why I drink only distilled water, or rainwater, and only pure-grain alcohol?
Group Capt. Lionel Mandrake: Well, it did occur to me, Jack, yes.
General Jack D. Ripper: Have you ever heard of a thing called fluoridation. Fluoridation of water?
Group Capt. Lionel Mandrake: Uh? Yes, II have heard of that, Jack, yes. Yes.
General Jack D. Ripper: Well, do you know what it is?
Group Capt. Lionel Mandrake: No, no I don't know what it is, no.
General Jack D. Ripper: Do you realize that fluoridation is the most monstrously conceived and dangerous Communist plot we have ever had to face?
General Jack D. Ripper: Mandrake, do you realize that in addition to fluoridating water, why, there are studies underway to fluoridate salt, flour, fruit juices, soup, sugar, milk... ice cream. Ice cream, Mandrake, children's ice cream.
Group Capt. Lionel Mandrake: Lord, Jack.
General Jack D. Ripper: You know when fluoridation first began?
Group Capt. Lionel Mandrake: I-- no, no. I don't, Jack.
General Jack D. Ripper: Nineteen hundred and forty-six. Nineteen forty-six, Mandrake. How does that coincide with your post-war Commie conspiracy, huh? It's incredibly obvious, isn't it? A foreign substance is introduced into our precious bodily fluids without the knowledge of the individual. Certainly without any choice. That's the way your hard-core Commie works.
Group Capt. Lionel Mandrake: Uh, Jack, Jack, listen, tell me, tell me, Jack. When did you first... become... well, develop this theory?
General Jack D. Ripper: Well, I, uh... I... I... first became aware of it, Mandrake, during the physical act of love.
Group Capt. Lionel Mandrake: Hmm.
General Jack D. Ripper: Yes, a uh, a profound sense of fatigue... a feeling of emptiness followed. Luckily I... I was able to interpret these feelings correctly. Loss of essence.
Group Capt. Lionel Mandrake: Hmm.
General Jack D. Ripper: I can assure you it has not recurred, Mandrake. Women uh... women sense my power and they seek the life essence. I, uh... I do not avoid women, Mandrake.
Group Capt. Lionel Mandrake: No.
General Jack D. Ripper: But I... I do deny them my essence.
