I sell games (see my link below). We have two games that are perfect for this...Take Your Pick would be my first choice and a second choice is the Let's Chat key ring.
If you wanted to make your own version of Take Your Pick, you would think of two words that are opposite of each other (sweet/sour inside/outside fiction/non-fiction for example). You guess which way you think the other person would answer and see if you are right. So...you would say sweet or sour and see what the other person says. You can do things like tv/radio movie/book desert/jungle dr. phil/mother teresa. Whatever you like
