There's an element of pop-psychology in the robbermask bit, reminiscent of the way Alan Funt would come up with Candid Camera skits that would really illuminate the way we think (like putting a box with a button on it on the counter of the dry-cleaner they often used for bits. Pushing the button caused the box to emit loud, random sounds with no way for the victim to shut it off. There was a sign that said, "Do NOT push this button!"...)
I about died laughing because I saw it as an extreme form of what I've gone through when I'm 'read' while en femme, and now am increasingly getting even when dressed unisex. (If they stare too much, I ask them if I have spinach in my teeth or something on my face...)
Now, where are these other bits you mentioned, Dennis?
