Two quarrelling boys were raining insults on each other. The 1st one said: "your family is so poor i could feed y'all with my pocket change". Everybody laughed. A little. The 2nd one, furious, replied: "And your home is so untidy it's as filthy as a toilet!". Everybody burst out laughing. The second boy began walking away, feeling victorious. Then a good friend called him and said: "Do you know you've just told everyone your toilet is filthy?"
