In the movie Brave, Merida introduces her three brothers, Hamish, Hubert, and Harris, as such:
The princes: Hamish, Hubert and Harris. Wee devils, more like. They get away with murder!
Normally, one would assume Merida is making the assertion idiomatically, however later in the film, we see the three boys participate in the throne-room brawl by dropping what appears to be a large morning star onto the head of a member of Clan Dingwall:
The weapon imparts enough force to cause the man's head to literally break through the stone floor, likely causing sufficient trauma for rapid, if not instant death. Meanwhile, the surrounding brawl, while likely to result in a few broken bones, appears largely non-fatal.
Normally, the boys' actions could be dismissed as unrealistic slapstick violence, however nowhere else in the film does any character suffer any trauma even remotely close to the level present in this scene. The only thing that comes close is when one of the great circle stones crushes Mor'du, though this clearly does kill him.
After the brawl scene, the boys' actions are never again discussed. So, do the three brothers actually get away with murder?
