It was a party and the host was getting worried because there were too many people and not enough refreshments. She was sure that not all these people were invited but did not know how to tell which ones were the crashers. Then the husband got an idea.
He turned to the crowd and said, ‘Will those who are from the bride’s side of the family stand up please?’
About twenty people stood up.
Then he asked, ‘Will those of you who are from the groom’s side of the family stand up as well?’
About twenty five people stood up.
Then he smiled and said, ‘Will all those who stood up please leave, this is a birthday party!’
