In a bad mood, who will tell me a joke?

An old man went to the store to buy soy sauce and found a box of Viagra next to it. The old man didn't know what it was, so he asked the clerk what it was. The clerk is a little girl, so I'm embarrassed to say that, so I looked at the old man and said, this is for your use below. The old man immediately bought it home and ate a bowl of noodles with Viagra in it.

There was an old couple who wanted a perfect bed life, so they went to consult a doctor. The doctor prescribed them two boxes of Viagra and told them to use it before sex. After a while, the old lady came to the clinic by herself. The doctor asked the old lady if the medicine was effective. The old lady replied excitedly: so effective. Now my old man's coffin can't be closed.
