Since we're sharing campground stories...
This summer we went traveling with our pop-up camper. We spent several nights at each campground, usually in fairly close proximity to our neighbors.

One night we got new neighbors, a rather fit young couple in a dome tent. We never spoke, but they seemed nice enough- cuddling at the lake shore, sitting together by the fire, all that.

They got into their tent, and after the predictable shadow show of them undressing (no sexing, though) their lights went out and all became quiet. As we had slept well the night before, we were sitting up by the fire quietly talking when the stillness of the night was shattered by flatulence of bovine proportions. All was silent again for a few moments, then the sound of feminine giggling started from the tent, followed a moment later by him following suit.

So the overheard secret was that hot girls do in fact fart. Loudly.
