"Is your head shaved?"
I looked up from the register and checked the man's eyes. Yup, they seemed fully functional as he was staring at my cleanly shaved scalp.
"Yes, it is."
"Mr. Bones! Mr. Bones!" He immediately began to chant in a sing song voice, "That's what I am going to call you from now on. Mr. Bones! Mr. Bones!"
He continued to sing that until left the store. Delightful.
