Initially, we started with jokes and anecdotes, but after 10 days we ran out of jokes. That's when I got my breakthrough. Why not laugh for no reason? People were sceptical.. Laughter is infectious and pretty soon all simulated laughter turns into regular, stimulated laughter. Anyone can laugh for 15 to 20 minutes without recourse to jokes... Laughter cannot be only amusement and entertainment. Real laughter is your nature. Madan Kataria, Founder, Laughter Club International.
