Everybody loves a great sports rivalry, but c'mon now. 

A photo has been posted on Twitter on the @PSUBarstool account of a pretty low-blow joke that some Penn State students made against the Michigan Wolverines.

Yeah, we know that people are over-sensitive these days. But really, there's NOTHING funny about our water crisis.

And Penn State? REALLY?? There's a MILLION not-so-funny jokes we could make about you guys, but we don't. So, choose your words more carefully.
