Damn Aussies

reports:

Other incidents included a 25-year-old Australian man being arrested for urinating on a shop window and into his own mouth. He was charged with offensive behaviour.

One has to be seriously intoxicated to think that is a good idea!

On a technical front, suspect that is quite difficult to do. You would need to have quite a strong flow, point upwards, have good aim, calculate the angle just right for the rebound and also allow for the effect of gravity.
