Until I was about 28, myself and my whole group of friends would 95% of the time give bullshit (usually whatever was funniest) answers to anything resembling a poll. Didn't matter how 'private' or anonymous. We thought polls were bullshit, and we treated them thus. Other classmates, even more than us, filled them out as the person they wish they were.

We CAN'T be unique...this happens a LOT!
