Dang, that beats my killings. I've built a fly guillotine before, it's just hard to use it. I've also held public executions of flies with my friends before, by slicing them in half and flushing them down the toilet while playing the Russian anthem
That's nothing i gathered a bunch of flies and removed their wings, tied them up and let them see their families getting raped by other flies and then starve them to death and feed them to ants infront of them
