So he asks his father

Johnny fell In love, so he asks his father.

“Daddy, I fell in love and want to date this awesome girl!”

“That’s a great son, who is she?”

“It’s Sandra, the neighbor’s daughter”

“Ohhh I wish you hadn’t said that I have to tell you something son, but you must promise not to tell your mother, sandra is actually your sister.”

The boy is naturally bummed out, but a couple of months later.

“Daddy, I fell in love again and she is even hotter!”

“That’s a great son, who is she?”

“It’s Angela, the other neighbor’s daughter.”

“Ohhhh I wish you hadn’t said that, Angela is also your sister.”

This went on a couple of times and the son was so mad, he went straight to his mother crying.

“Mum I am so mad at dad! I fell in love with six girls but I can’t date any of them because dad is their father!”

The mother hugs him affectionately and says:

“My love, you can date whoever you want don’t listen to him He isn’t your father.”
