3 expecting mothers were talking in their doctors office, about the sex of their babies.
The first mother said, “I’m having a boy.”
“How can you be so sure?” asked the other two.
“Well” said the first, “my husband was on top.”
The second replied, “If that’s the case then I’m having a girl because I was on top.”
The third started to cry. The first two asked her what was wrong.
“I’m going to have a puppy” she replied.
