The young Irish lad comes home full of joy, and says to his mother, “Mom, I found the girl of my dreams and I want to marry her, but tomorrow I want to test you.”
So next day he comes home with three girls and has them sit on the couch, and says, “OK mom, I want you to guess which girl I love.” The mother takes her time and talks to each girl, then she points to the girl in the middle.

“That’s right, mom!” says Pat, “How did you guess?”

“I dont like her!”
