Could this be made into an actually playable game? How many sessions could you play and still have a social circle?

Once it starts getting personal, it's all over. A game I used to play with my friends was just debating random propositions (I once defended with considerable success the proposition that puppies are tender and delicious.) I think this was as useful simply to see what pleased the onlookers the most, and there was little chance that someone might say something like 'John's acne is truly grotesque'. How many non-personal, awful truths does anyone know, or could people agree on?
