Never Ever Did I
This is another option which is absolute fun. All you need to do is prepare a list of things on a paper titled "Never ever in my life did I...", and include things like 'Have a one-night-stand', 'Drink & drive a car', 'Sunbathe nude on the beach', 'Cheat on a boyfriend', 'Date a married man', & similar things, which usually wouldn't be discussed willingly.
