My first job out of college was to train adults on how to use computers.  As I would begin a class, I would inevitably stumble through my words because I was a bit nervous and would be talking too fast.  At this point, I’d have the opportunity to take a breath and add a little levity to the morning.  I’d start out by saying “You’ll have to excuse me.  You see, I grew up hearing my dad tell me stories of Rindercella and at the moke of stridnight, she was running down the stairs and slopped her dripper.”
