well smack my bot-bot and tell me what colour undies i should wear!

Mostly I hate quizzes on T'Net that tell you random stuff that your never wanted to know.

But now that one's telling me what colour undies I should wear, how could I resist?

Your Lucky Underwear is Yellow

You're an extremely happy, laid back, fun soul. And your lucky yellow underwear can help you get even more out of life. In life, you rather play than work. You're apt to quit any task that doesn't nourish your creativity and inner child. Sometimes your drive for freedom hinders your quality of life. You find it impossible to do anything unpleasant. If you want to have responsibilities and still have fun, put on your yellow underpants. They'll help you make a party out of the most mundane tasks.
