An elderly couple is getting ready for bed. She says Oh I am just so hungry for ice cream and there isn’t any in the house.”
He says, “I’ll go get some.”
“Vanilla with chocolate sauce, with whipped cream on top and a cherry.”
She adds, “Please write it down, I know you’ll forget.” He says,
“I won’t forget; Vanilla with chocolate sauce, whipped cream, and a cherry.”
Away he goes. Hours later he comes back and hands her a paper bag.
“In it is a “HAM SANDWICH”. She says,” I told you to write it down! You forgot the mustard.”
