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 as well as my fiancée and you try and guess which one I'm going to marry".

The next day, he brings three beautiful women into the house - a blonde, a brunette and a redhead. He 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."

Without a moment’s hesitation, she says, "The redhead in the middle."

"Ma, that's amazing! You're right, how did you know?"

"I don't like her."
