Guess Who's the Fiancee

A young man excitedly tells his mother he's fallen in love and is going to get married.

He says, "Just for fun, Ma, I'm going to bring over two other female friends in addition to my fiancee and you try and guess which one I'm going to marry".

The next day, he brings three beautiful women into the house and sits them down on the couch and they chat for a while.

He then says, "Okay, Ma. Guess which one I'm going to marry."

She immediately replies, "The red-head in the middle."

"That's amazing, Ma. You're right, how did you know?"

"I don't like her."
