*An old man, heading home after a game of chess, got hit on the head by an empty can dropped from a window as he walk into the void deck.

Upon returning home, he was greeted by his ever cheerful grandson, who was looking at the bump of pain that he is desperately trying to relieve, and asked: "What Happen?"

The old man, who only understand English but can't speak it, replied in what the little boy thought was gibberish. The boy, confused, requested his grandfather to repeat his statement.


So, the old man said in dialect again, this time louder: "Gong gong gong, gong gong gong gong, gong gong gong gong!"

公公晕，罐敲公公， 公公晕晕!!

tangent lines who had once chance to meet and then parted forever

parallel lines who were never meant to be together

asymptotes who can get closer and closer but never get together
