We used to play a car game when the children were young. What is Mom's favorite song? What is Jonathan's favorite food? We would each guess, and then be given the correct answer by the referenced person. One episode became legendary in the family, when the question was What is Dad's favorite color? and Ben, likely about seven, answered with a snigger "White, with coffee stains." Ouch.
My oldest son turned 30 today and spilled coffee. I am 30% amused by this and 70% wincing in embarrassment and having bequeathed this life to him.
