Like I've mentioned before, kids can be evil. (Or was it "kids are evil", I can't remember?)
We have our childhood stories of how we used to set ants on fire, kill our goldfishes with mummy's medication and, launch terrapins up in the air for sport. (Disclaimer: these are really other psychopaths' stories :D)
I can't say I've drenched a rat in kerosene, set it on fire and open the cage door because I'm just so terrified of rats. Neither can I say I've caught a grasshopper and taped it to the blade of a fan and turned it on because giant flying insects scare the bejeezus out of me.
All I did was drip wax, burn or, stomp on ants and pull the legs/wings off mosquitoes. Can't say I've had much experience in this field.
Now as adults, we know this is wrong. Well, most of us. But as adults, when you share these kinds of stories with each other, you'll have a ball of a time! You'll cringe but you'll always end up laughing your asses off.
What sort of crazy crap did you use to do to animals and insects?
