Laughter is a mystery. It is better to experience it than to hear someone talk about it. But one becomes curious, “What is laughter?” Laughter is the most intelligent factor in you. Buffaloes don’t laugh, and if you meet a buffalo laughing you will go mad! Then it will be impossible to bring you to sanity. No animal laughs. Laughter needs a very sensitive intelligence. It means that you can understand the ridiculousness of a certain situation.
