I filed a patent...
...it's for something I have named "walking". It involves lifting one foot from the ground and moving it forward while leaning slightly forward. this causes the weight to shift and the body to begin to fall forward at which point you put the now front foot down onto the ground. You then repeat the action with alternating feet until reaching your destination.
Anyone who uses this method of travel is hereby infringing on my patent and will shortly be hearing from my lawyers.
No point taking it to court in the USA though as mostly they use the alternate "waddling" method which you are forced into once your weight becomes too much for your legs to properly support and your thighs too fat to close your legs properly.
