During an off-peak period of the day, a little old man shuffled slowly into an ice cream parlour and managed to pull himself up, slowly and painfully onto a stool, the waitress appeared before him.

After catching his breath, he asked, “May I have a banana split, please?” The waitress then asked kindly, “Crushed nuts?” And he replied, “Oh! No, Arthritis.”
