NOTE: All of the violence in the film is intended to look fake, in keeping with its absurdist nature; red Crayola paint is used as fake blood, and much of the violence is played for laughs.
A man has a bloody scar on the left side of his head in the beginning of the film. He later cleans the wound using hydrogen peroxide, and in a shot showing the inside of his head, we see the substance react with his blood.
A man pulls out three "bullets" from his body. No blood, but the man reacts with a slight amount of pain.
A man is shot by accident. We see the gun that killed him on the floor completely covered in blood. This scene is played for laughs.
It's heavily implied that a man chops up the corpse of another man. We don't see the act, but we do see what appears to be the corpse's head stuffed in a freezer.
A man "accidentally" fires a gun in a car, which startles both him and another man.
There are three scenes in which a character is held at gunpoint by another. Nothing happens in any of these scenes.
Three men are shot off screen. We see the aftermath and there is a moderate amount of blood.
Two men are beaten with a cheese board.
A man is stabbed twice. There is no blood and we don't see the penetration. Directly after this, another man is shot, with no blood.
There is a knife fight between three characters. No blood.
