Today in class I asked a cute girl to start rating people on a scale of 1-10 by pointing at people (never asking about myself), eventually I asked who was highest on her scale out of everyone. She started giggling and wouldn't give me a straight answer. I then asked who 2nd and 3rd was and she gave very straight answers. It was then obvious that yours truly was the highest in the class.

Maybe I haven't perfected this technique and I've only used it on this one girl, but can anyone else share their opinions or experiences with this type of approach?
