An elderly couple was suffering memory problems. They went to the doctor and the doctor says: "Well, You are not ill but suffering from memory loss caused by age. You know what: Just write down everything so you will not forget."
The elderly couple thanked him and returned home.
The same evening they are sitting and watching TV and the woman asks her husband to bring her some ice-cream.
The man stands up and starts to go to the kitchen. The wife says, “Hey Write It Down like the doctor says.”
“What, for ice-cream?” he asks.
He went into the kitchen and came out 10 minutes later with fried eggs and toast. The woman takes a look and says, "I TOLD YOU TO WRITE IT DOWN. THERE IS NO BUTTER ON THE TOAST."
