The elderly couple was sitting in the den watching TV. They were discussing the fact that they sometimes experienced short-term memory loss. The wife decided that it might be a good idea to write things down to jog their memories. The husband agreed. 
During a commercial, the gentleman got up and told his wife he was going into the kitchen to get some ice cream. His wife asked him to get her some, too. He said, "Sure". She said, "You'd better write it down". He said, "For Heaven's sake, I can remember to get you your ice cream!" She said, "But I want a cherry on top, too. You'd better write it down". He replied that he was capable of remembering ice cream with a cherry on top. She said she also wanted some whipped cream on her ice cream and that he'd better write it down. He left in a huff, muttering that he certainly could remember ice cream with a cherry and whipped cream.
Several minutes later he returned with two plates of fried eggs and bacon. His wife was furious. She said, "I told you to write things down. You forgot the toast!"
