I'm not sure what you would call this but we discovered years and years ago my sister and I both "get" the answer when playing Trivial Pursuit and the person asking the question turns the card over and reads the answer before you've answered.

I won a Trivial Pursuit tournament in a local bar because I "got" the answers from several people when they turned the card over and read the answer. It would just pop into my head. I know I know loads of random useless crap but the answers were to stuff I actually didn't know.

Our family rule became "no reading the answer before the person has answered."
