This is more funny to me than anything, doesn't sound like anyone was "harmed" (meaning, nothing suggests he was intentionally trying to get people to look), so really, I can't see it being a big deal. If he's whipping his dick out and showing it to people who do not want to see it, that's one thing, this sounds like the dude was just in the mood to crank one out and didn't really consider the consequences.
Going to be a lot of jokes for the rest of his career (and life), though, and I will happily make them all.
Edit: Sweatpants around his ankles though man, that's the comedy cherry on this hilarious sundae.
