One time my mother and father were sleeping when my dad, who was prone to discussions and other shenanigans while asleep, sat bolt upright in bed and said "My leg!" while looking at mom.
Mom sat up and said "What's wrong?!?" while trying to feel his leg to see if she could help.
My father looked right at her and said "It's oriental!"
"OH GO BACK TO SLEEP, JIM!!!"
He did. Nothing was wrong and he had no memory of this event.
