Did you ever see that movie The Sword of Doom? It's about a swordsman during a time of unrest in Japan who is basically a serial killer who uses the political chaos of the times and the formalities of dueling rival martial arts schools to get away with murdering people. He enters a sword fighting exhibition that's to use non-lethal wooden swords but then he "accidentally" cracks people's skulls open. That's during the day. At night he uses real steel to assassinate the designated enemies of an extremist organization.
The guy is a real monster. By the end of the movie he's made enemies out of everyone, and a small army of swordsmen show up to kill him. The sinister swordfighter seemingly can't be beat as he slices and dices wave after wave of would-be assassins.
At one point during the protracted final battle, instead of charging into the fray, a circle of these foemen just start inexplicably throwing pillows at their target.
Why did they think that would work?
It doesn't, ultimately, but my guess is that they were so frustrated by their endless failures to kill just the one guy they were open to anything. After all, final boss battles are known to require both persistence and lateral thinking in order to succeed.
Sharpness has failed.
Why not try softness?
That doesn't work, either, but give the guys credit for trying things out!
