You see a mantis sitting on a flag and you know for a fact that it does not belong there. Insects should be in trees and on the ground. Not on flags. Insects belong in the wild!
Luckily for you, and unluckily for this mantis who doesn't belong on your flag, you're a Bosozoku (ぞく) bike gang member, and you don't take crap from nobody. You climb the flagpole, punch the mantis and yell, "YOU DON'T BELONG HERE!"
