Meeting the parents Joke

While they were eating, it started raining heavily so the girl’s mother said; ‘Akpos, I think you should sleep over here because the rain is showing no sign of stopping any time soon’.
After eating, the mother went to the toilet and the father went to sleep, while the girl went to the kitchen to clear the plates.
When the girl and her mother returned to the sitting room, Akpos was not there, they checked all over the house and did not find him. As they were wondering, what had happened to him, he walked back into the house, wet and soaked with a plastic bag.
The Girl’s mother asked; ‘Where were you, and why are you so wet?’ Akpos replied; ‘I went home to get my pajamas!’
