So, a couple of days ago, Pup had Casey all day, while I was at work. When I got home, and it was time for the shift change, she mentioned that poor Casey was constipated, and hadn't pooped all day. Casey and I were hanging out on the couch, probably watching NBA basketball. All of a sudden, he seemed to cure his constipation problems, ALL AT ONCE. Sitting in my lap, he just kept going and going.. Kinda like the Energizer Bunny... Finally, when I didnt hear/ feel any evidence of further emitting waste, I decided to change his diaper. I went to unbutton the onesie, and saw evidence of soiling... on his stomach! Not letting that deter me, I proceeded to unlatch the diaper... That S(*&^ was EVERYWHERE! It was beyond wipees... I latched that diaper right back up and marched Casey to the bath. Filled the tub, and dropped him in.. pretty much needed a full body bath to clean the aftermath.. Reminded me of a roommate I had in college. He would go into the bathroom... sit for about 15 minutes, then I would hear the toilet flush, sometimes 2-3 times, followed immediately by the shower turning on... EVERYTIME!
What are the odds? Pup has Casey ALL DAY... nothing. I have him for 10 minutes and he explodes. What am I, a natural laxative? Or kinda like the situation in Las Vegas where someone spends all day feeding money into a slot machine.. only to get shut out. Fresh out of money, they get up to leave and the lurker swoops in and put one quarter into the same machine that was just vacated... JACKPOT...
