Would you rather make kittens spontaneously explode when you look at them or be return to your Year 7 self (reversed puberty and all) for 10 years?
Oh god, I was an annoying turd in year 7, I was so weird! But killing kittens with a glare isn't exactly normal... damn you. I'd have to go with kitten exploding. Eh, I guess I'm not exactly normal even now
