There are the obvious things that will give you swine flu—like getting sneezed on, for instance—and then there are the painfully obvious things that will give you swine flu—like playing beer pong.

We could probably file this under “Obvious Science,” but officals at Rensselaer Polytechnic Institute in upstate Troy, NY have warned students that the sharing of cups during games of beer pong lead to the spread of disease, and especially of the spread of H1N1 this flu season. The same officials sent out a campus-wide email detailed a group of students who had all come down the virus after a weekend game.

Area schools are reporting many cases of the swine flu; RPI, a school of about 7,000 total students has reported 21 cases this semester so far.
