There are some things that you can only really say aloud, as when entered without context or inflection online they can sound a lot different. While this is pretty 'duh,' I bring it up to reference something specific.

Whenever anyone loses something, almost without thinking I'll ask: "Did you check in your butt?" Which is naturally hilarious the way I say it, and I'm sure no one is sick of me responding in this manner. (Wink wink)

Someone on facebook posted that they lost their debit card. I had "Did you check in your butt?" entered into the comment box and was about to hit enter when I realized that by itself, might seem like a dick thing to say. Add that to the fact that I don't hang out with the girl who posted it, and she's never heard me say that. Not that she would jump straight to offended, but it would have registered on the 'inappropriate' scale.

Man my job leaves me with massive amounts of free time in front of a computer. This could be bad.
