If this was a psa about not spreading germs, which phrase would make the best slogan?

To prove how easily someone can spread germs from not washing his or her hands, people start to whistle “In the Hall of the Mountain King” once they have germs on their hands. Soon enough, an entire city is whistling. It’s likely a nod to the classic German thriller M in which a child killer starts to whistle the eerie tune when hit with the urge to kill a child. Given just how many people are whistling here, it seems we’re all potentially about to commit murder with our dirty, germy hands.

c. spelling errors, if not i am so sorry. but i hope it !
