Two old men suffering from long term memory loss were sitting on the steps of the old age home when an ice cream van drove past.
"God," said the first old man, "I would love an ice cream right now!"
"Would you like me to get you one?" asked the second old man.
"Are you joking?" said the first, "You would forget my order straight away!"
"No I wouldn't!" replied the second.
"All right then," said the first, "I want a double cone with mint ice cream and chocolate chips and a cherry on top."
The second old man repeated the order flawlessly. Five minutes later he returned carrying two hot dogs.
The first old guy looked at the hot dogs in disgust then yelled, "I knew I should have gone myself. You forgot the fucking sauce!"
