When we are waiting at restaurants, doctor's offices, etc., we play lots of the same games as you probably do, but my son invented a fun game that you might like. It's called "two minutes" and it is similar to twenty questions. One player thinks of a person, and the other has exactly two minutes to shoot as many yes or no questions as possible and get the answers. This is usually enough time to guess the person. It is more fun than twenty questions, and it is easier for kids, because you get to ask lots more questions.
