One evening Dave was at home watching TV and eating peanuts, tossing them one by one into the air and catching them in his mouth. While he was in the middle of catching one, his wife asked him a question and as he turned to answer, the peanut landed in his ear. Dave's wife tried to remove the peanut but only succeeded in pushing it deeper into his ear canal. With all subsequent attempts to remove the peanut failing miserably, the pair began to panic and decided to go to the hospital. However, just as they were about to leave, their daughter came home with her boyfriend.
Hearing of the problem, the young man told Dave to sit down, then proceeded to shove two fingers up Dave’s nose and told him to blow hard. Sure enough, when Dave blew, the peanut flew out of his ear. Everyone congratulated the young man and the daughter took him into the kitchen to get him something to eat as a reward.
The relieved wife turned to her husband and said "Isn’t he smart? What do you think he’s going to be when he grows older Dave?" The father replied "From the smell of his fingers, our son-in-law!"
