There was a party with lots of eating and drinking.
The host was getting worried because there were too many people and not enough refreshments.
Host wasn’t sure if all of them were invited or not.
Then he got an idea.
He turned to the guests and said, “Will all those from the bride’s side of the family please STAND UP?”
About 20 people stood
Then he asked, “And from the groom’s side?”
About 25 more people stood.
Then he smiled and said, “Will all those who stood please leave, this is a birthday party”.
