I have horrible habits of saying things that can be interpreted in the WROOONG way when trying to explain things. Akin to, "No, you have to put it in SLOWLY!" or "That's the wrong hole." I mean, you can imagine it the wrong way, or you can think of "If you put the egg into the boiling water too fast, it will break" or "Don't put a square block into the circle shaped hole". It's just the scant way I tend to scatterbrain-ed-ly explain things that causes problem. Usually a friend will be like "Sarah!! What are you saying???" and I'm left wondering why my friends have such horrendously dirty minds.
That said when it comes to actually DOING something that looks wrong, I've little experience. Usually it involves more stupid sex jokes that form in the mind of horny teenagers.
I think the worst is once I somehow managed to get a popcorn kernel right down my shirt and it continued down to my jeans, which were just loose enough for the kernel to fall through. And I was jumping about and shaking and trying to get it out without having to go to the bathroom and go searching, and someone asked me if I just really had to go use the bathroom. And once one of my friends reached over to grab a bit of food that had fallen on someones front (notably, female. Boobs and whatnot) and was asked if she was groping the other friend. Polite action in one movement turned into something sexual to the foreign eye. Sigh.
