A joke about an 80-year-old man

It is also a good choice for a man born after 80 to marry a 20-year-old girl when he is 40, if conditions permit.

I finally turned 40 and found a beautiful young 20-year-old girlfriend.

Go to her home to meet her parents.

The door was opened by my first girlfriend who had been together for several years in college.

The new girlfriend shouted: Mom ~

Add on the third floor: Her mother gasped when she saw me. Unconsciously, I pulled my daughter into the room and said to her, "You can't be with him, he is your biological father!" " "

Daughter: I have his flesh and blood. ...

On the 5th floor, the girl's father in his 60s came out and saw her boyfriend. He whispered to him, "Why are you here? Isn't your mother and your living expenses paid on time every month?

On the sixth floor, at this moment, the girl's boyfriend's mother "Ding Dong" came to see her in-laws and met the girl's father: "How did you ..."

On the seventh floor, the girl's boyfriend's father stopped the car and went upstairs. When he saw the girl's father, he immediately burst into tears: "Aren't you my long-lost brother?"

On the eighth floor, the girl's mother saw her boyfriend's mother: "Mom!" "

The girl mother on the ninth floor saw her boyfriend's father and shouted "Dad!" , immediately fainted.

Q: 1. What floor can you understand?

2. What's the name of the boyfriend's mother when she sees her girlfriend's mother?
