A boy comes home from school looking furious. He goes up to his father and says, "I want to kick Hitler square in the damn balls!"
The father, shocked by his outburst, asked, "Why son?"
"Because that fucker was intolerant of other religions and that asshole killed 6 million Jews!"
The father leaned in towards his son and hissed, "Keep it up with that mouth and you'll be one of them."
