Here's a little followup to wearing the "Tickle Fight" T-shirt:
I've worn it out in public a few times already, mostly getting very little notice. I was out at the lake and a young man walking his baby in a stroller did take a long hard look while walking past, but did not stop nor ask anything.
Yesterday, just as I was about to leave a supermarket, a short middle-aged handsome fellow turned and said "I was going to tickle you, but..." I laughed in response. He laughed and said, "I love that shirt!" I will certain be back, as I know he works there (I think he's an assistant manager).
No negative responses to the shirt as of yet.
