separating your nads with your boxers, creating an effect that, well, looks like a fly. Then you chase any unsuspecting friends/family/colleagues/children with. May result in jailtime.

In New Orleans, the public park area between the Audubon Zoo and the Mississippi River. This area once featured a garish example of low-budget 1960's kitsch architecture that resembled an abstract angular fly and was last used to rent roller skates. While the building was destroyed long ago, the locals still refer to the park as "The Fly".

There is an art, or, rather, a knack to flying.
The knack lies in learning how to throw yourself at the ground and miss.

Pick a nice day, and try it.

The first part is easy.
All it requires is simply the ability to throw yourself forward with all your weight, and the willingness not to mind that it's going to hurt.

Clearly, it is the second part, the missing, which presents the difficulties. You have to miss the ground accidentally.

If you are lucky enough to have your attention distracted just in time, please take note of the following: ignore all consideratinos of your own weight and let yourself waft higher, do not listen to what anybody says to you at this point because they are unlikely to say anything helpful (They are most likely to say something along the lines of "Good God, you can't possibly be flying!" and it is vitally important not to believe them or they will suddenly be right). Waft higher and higher, try a few swoops, DO NOT WAVE AT ANYBODY.

Landing is another story.
Arthur Dent suddenly tripped and was hurled forward by his considerable momentum. But just at the moment he was about to hit the ground astoundingly hard he saw lying directly in front of him a small navy blue tote bag. In his astonishment he missed the ground completely and bobbed off into the air.
What Arthur was doing was this: he was flying.
