Most ticklish?
Oh, and one more thing. It might be a good idea to conduct a study on whether it's the boys or the girls that more DESERVE to be tickled. That would prove what we already know, that if anyone DESERVES to be tickled, it's the lasses.
Seriously, who is it that paints ceilings in the home? Then when the painter just about has HIS arms used up from wielding brushes and rollers, who is it that walks in wearing short white shorts and a pink halter top and says, "You missed a spot over here."(hmmm???)
Who is it that sits on the passenger side of cars and asks questions like, "Why did you go this way if you knew you were going to get lost?" (hmmm???)
Who takes minor flaws and tosses them in you path..."You know, a little gray hair makes you look distinguished...or is it extinguished...I can never keep those words straight." (hmmm???}
Finally, there are assigned tasks in any good marriage. Mine is to make the rules and hers is to follow them. For instance, I made a rule even before we were ever married. There are to be no, nada, none, zip, flannel night clothes in this house. Then, with the first dusting of winter snow, year after year, I climb into bed, reach under the blankets for my usual female exploratory. What do I find? You guessed it. Flannel! And pajamas no less!!! Do you know evil? You are expecting the delight of fingers on female and you get fingers on flannel! Worse yet! The wench giggles at you! This is going to be a tickled woman, and right now! She deserves it and she knows it!
I don't think there is any doubt, it's the women that deserve to be tickled, regardless of which sex boasts the most ticklish people.
