Zak had no problem letting me know that he was extremely ticklish. 10 out of 10 is what he said. But, he tried to convince me that his upper body isn't very ticklish and that his most ticklish spot would be his size 14 feet. Well, needless to say, I discovered just how incredibly ticklish he is on his upper body as well! "I told you I'm very ticklish!" I know Zak, but now it's time for me to do my own research into the matter!
