Situation (Read at your own risk if you have a delicate constitution)

It is 7:45pm the kids are in bed and you are a few dishes away from a clean kitchen and a cozy spot on the couch with the Desperate Housewives, when all of the sudden your stomach gurgles. You know the one I am talking about. The one that says 'you had better get the the bathroom ASAP'. But you are like me, and you know that if you leave this chore unfinished, you won't came back to it. And what would the flylady say? So you wash and dry that last pot with a speed you didn't know you possessed and put it away. You squeeze your cheeks as you spray out the sink, empty the food traps of their noodles, and shine that sink with some windex. We have done the flylady proud. Now as you dash for the bathroom your very recently potty trained son comes around the corner with his underwear around his ankles. "I have to poop" he says. Well crap...you know this isn't going to go quickly, especially because he is supposed to be in bed and he will do anything to be out of his room, even if it is sitting on the pot for 15 minutes. But you know he hasn't pooped yet today, so you can't make him wait otherwise, not only will you have tummy trouble, but you'll be cleaning up his BM off the bathroom floor. So...what do you do??? Tell me....WHAT DO YOU DO?
