Believe it or not. There are 400 different gases in a human fart.
It is believed that collectively the Japanese produce 80 million liters of Fart Gases every day. Now a great innovator had a bright idea. If all the people could be synchronized via the internet to fart on a cue, they would emit 4.2 billion liters of butt gas. This would be some amazing power for countries with huge manpower resources to posses.
Ever wondered why your friend’s farts are especially smelly ones these days. Experts in this field point to dieting as the main culprit. Dieting leads to a loss of muscle tissue in general, and loose stomach muscles in particular, which in turn leads to constipation, and farts that would make even Doug blush!
