Hold Your Water

What is it with men and public restrooms? Why can't they leave it looking like they found it?  I returned to work today and was told by our maintenance guy that the restrooms were out-of-order yesterday because some guy had wee'd on the toilet paper dispensers.  I mean come on!  As young boys, you guys learn the skill of writing your names in the snow.  Why can't you carry that accuracy and precision into adulthood?  Or as my grandma used to say "learn to hold your water!"
