You show up to that $40 10K race with $25 in your pocket. You hand over the $25 with your late entry registration form.
I'm sorry Sweetie, says the lady at the table, you need $40 for the entry fee. (note here a great advantage to living in South Carolina. You get to be called Sweetie all the time)
I explain that it is my policy to only have $25 in my pocket at any given time. It's a policy that generally keeps me out of trouble.
Well, there is no shirt and you are the last one, so OK we'll go with it. You remember me now OK?
Thank you Sweet Heart; I will.
