My Take
This is different from every other take on this Tickle Chair episode. This girls is obviously uptight about anything related to sexuality. So it is highly unlikely she would openly admit to something with sexual undertones like ticklishness. If you watched the episode, you saw how repressed she seems. Plus, she has career opportunities to think about. Maybe she was thinking, or her publicist suggested, that giggling in a tickle chair would take some credibility or damage her image. I think she actually denied being ticklish and here are my reasons.
1. When Stuttering John was "feeling her out" for ticklish spots, she flinched her feet when he went down by her feet.
2. She never denied being ticklish before the interview. A lot of girls on the show have said they weren't ticklish when the tickling was suggested. She never denied being ticklish beforehand. She even seemed apprehensive, asking if 60 seconds in the tickle chair could be lowered to 45 seconds. Why would a non-ticklish person care how long they sat there?
3. When tied to the chair at first, you can almost see a look of nervous concentration, almost as if she is psyching herself up not to be ticklish.
4. When tied in the chair, she crosses her feet over top of each other, almost as if to protect her soles.
5. When the foot tickling actually starts, she does giggle and flinch at first. Either becuase of willpower, or Stuttering John's horrific techniques, she regains and maintains her composure.
6. Stuttering John is THE WORST TICKLER EVER!!!! He should be beaten with a stick. Her makes some of the women from FM Concepts and Cal Star Videos look like Priscilla James or Sharon Kane. Stuttering John should be refrained from tickling anyone in the tickle chair. Bring in Robin to do the tickling. She seems like she would be sadistic, and I would bet she has good nails.
If you doubt my hypothesis, go back to the video tape. Take my reasons with you, and see my perspective. If necessary I can do a Kevin Costner in JFK reviewing the Zapruder film:
"If you look at her sole when the hand approaches, you'll see it goes back, and to the left. Back, and to the left. Back, and to the left."
