Personally, I don’t think tops need any ideas. They are too creative by half. However, the following passage from a vanilla craft blog was so cute I’ve decided to risk putting ideas into somebody’s dangerous head:

Uncle David was in high school already and he had regaled us with stories of the electric paddle kept in the principal’s office. I had visions of an electric ceiling fan-like contraption into which a child would be strapped and the beating would commence! Rachel reassured me that he was only pretending – but I still spent first grade being VERY good! I didn’t want to take any chances! Hmmm… I wonder if my boys would fall for the electric paddle story?

Actually, I’ve just remembered that our friend Domino owns an electric fly-swat, which she calls a “sub swat”. So somebody has obviously had the idea already…
