Inadvertently singing inappropriate lyrics out loud whilst at work.
Potentially embarassing, yes? I'm on my own in my bit of the office at the moment and thus am liable to being unself-conscuious then suddenly discovering someone's walked into earshot.
In other news a couple of days back I was wandering along a remote rural road in Scotland, got carried away listening to what I was listening to and started dancing around the road in a ridiculously over-the-top manner. I was pretty confident no-one would come along but would have been terribly embarrassing if they'd done so. In the end the only net result of this dancing was that the Scott 4 CD I had in my pocket fell out, rolled across the road and down an embankment which I had to climb down to rescue it.
