I'm just thinking out loud, but maybe I should introduce the new guy with Tourette's to Hockey Helmet Kid

I had this conversation with the new guy from work with Tourette's. It didn't go very well:

"Why 'Cupcakes!'?" I asked the new guy with Tourette's.
"What?" he said.
"Why do you always yell, 'Cupcakes!' in the middle of staff meetings?"
"Does it really matter?" he replied.
"No, I guess not... Hey, would you like to meet a kid on my street who wears a hockey helmet all day long? I think he may be retarded."
"William," he said, a bit perturbed, "I have Tourette's; I'm not retarded."
"Well," I responded, "let's not split hairs, okay?"
