General Jack D. Ripper: You know when fluoridation first began?
Group Captain Lionel Mandrake: I... no, no. I don't, Jack.
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.
Mandrake: Uh, Jack, Jack, listen, tell me, tell me, Jack. When did you first... become... well, develop this theory?
Ripper: Well, I, uh... I... I... first became aware of it, Mandrake, during the physical act of love.
Mandrake: Hmm.
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.
Mandrake: Hmm.
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.
Mandrake: No.
Ripper: But I... I do deny them my essence.
