The Sports Guy knows about this topic. He even came up with a scale for it. It can come up at any time, anywhere, any place. Something happens that seems so innocent/naive that our silly, twisted minds turn it into something we find in the gutter. I, for one, fully embrace unintentional comedy and the chuckles it leaves me (and my friends) with.
So if you don't know what I mean by this, check out this link to these comic book panels that, back in the day, had no idea how many sexual vernacular/euphemisms would arise so many decades later. Of course, Batman and Robin make several appearances, but Lois Lane's antics should have been number one.
