Well, for starters . . .
I think this incident clearly illuminates why it's a bad idea to give birth to male children. They're always doing stuff like that.
I think this incident clearly illuminates why marriage should be banned. This is always happening to married couples. If it's not guns, it's frying pans and fists. Marriage is clearly a bad idea.
I think this incident clearly illuminates why no one should be allowed to conduct his life without constant medical supervision. Any time you allow individuals (or couples, in this instance) to run around, indiscriminately living life, bad things happen. A psychologist should be appointed to every marriage. Later, when we have enough psychologists, we should assign one to each individual. Uncontrolled people just screw things up. We need to get better human controls in place.
Shall I go on?
