Ants are cool.
When I was little I used to like making ants from different colonies fight.
One time, for science class, I made a group of red ants fight some black ants, but they were too evenly matched. I tossed a fire ant in there, and every single one from both sides (had to be dozens of them) ganged up on it.
It killed them all. Ripped their heads right off their bodies and wore their heads like bracelets around its legs (seriously, they'd bite around the legs and this mean fucker would just rip their heads off and leave the heads clamped to its legs).
Don't mess with fire ants.
