A young boy accidentally cuts his brother in half with a machete. This is played for laughs and not that graphic.
A man gets high on an unknown substance and goes on a rampage, flipping cars, running from cops, etc. Again, played for laughs.
A running gag is that whenever Dewey gets upset, he violently rips a sink out of the wall (parodying when angry characters randomly destroy things in films).
A man reveals to his son that he has been planning to kill him his whole life, and then proceeds to challenge his son to fight with machetes. He fights with his son but then accidentally cuts himself in half. Not that graphic and played for laughs.
In a montage, we see a man hold a switchblade up to another man's throat. In the same montage, a man uses another man as a human shield, who then gets blown to bits by unknown assailants. The man then emerges from behind his human shield and fires a revolver at them. In the same montage, a father holds a revolver on his son. Comical and played for laughs
Two men have a heart attack at the end.
