A man goes to see the doctor because he has a sore throat.

The nurse tells him to take all his clothes off and sit on the bench in the hall. The man tries to protest, but the nurse doesn't listen and just repeats the same orders then leaves the area.

The man complies with her orders and joins another naked man sitting on the bench. The man starts complaining to the man already sitting there, that he only has a sore throat and doesn't understand why he has to take all his clothes off.

The man who was already sitting on the bench nude, looks at the other man and says "You think that's bad, I'm just here to pay my bill."
