A teenage girl arriving home from school asks her mother, “Is it true what the teacher told us today?"
“What’s that?” the mother replied.
“That babies come from the same place that boys put their penises,” the daughter said.
“Yes it is dear,” mother said, glad that the subject had finally come up at school.
“But when I have a baby,” the girl responded, “Won’t it knock my teeth out?”
Good one Mate
