Spit in my Urinal will ya.....

I keep meaning to pose this question that keeps running through my mind.
Okay, not like I am obsessing over it, but since I drink nearly a gallon of water a day I spend a lot of time in the bathroom.
I do not understand why the majority of guys all spit before in the toilet/urinal before they pee??? Why do the majority of guys do this? Can they not begin the flow without spitting first? Kind of like how the sound of running water can make people need to pee, does spitting make your little guy work better? It must be the sound of splashing toilet water!! Yeah, that's it....it's gotta be....

Mystery solved....the sound of spit hitting toilet water stimulates guys to pee.
