This is glad I'm not in college anymore...
We've all heard about Beer Pong - the game younger adults play - by tossing balls in cups full of beer....well...they are full of bacteria!!!

A new study by Clemson University showed beer pong balls covered in bacteria like salmonella, listeria, E. coli and staph.

“90% of the bacteria”is probably harmless, but you do run the risk of getting what some call “pong flu.”
~Sorry...I'm a germ-phobe and gross out from stuff like this.
