A couple watches TV in the evening and the husband eats peanuts

A couple watches TV in the evening and the husband eats peanuts throwing them in the air to make them fall into his mouth.
At a certain moment, his wife who passes behind the couch, the shove and the peanut lands in his ear rather than in his mouth.
He may try to remove it, but the more he tries, the more the peanut sinks into the bottom of his ear.
Not knowing what to do they are about to call a doctor when their daughter comes home with her boyfriend.
The latter examines the father's ear, puts two fingers in his nose and asks him to blow, the peanut is then expelled from the ear.
When the girl and her friend leave, the woman asks her husband:
- This boy is talented, what do you think he will become later?
On which the husband, recovered from his emotions, responds impassively:
- Judging by the smell of his fingers, probably our son-in-law !!
