One of my dogs had a bout of diarrhea last night.  She squirted all over her kennel, and I found myself on hands and knees, using Fantastik and paper towels, trying to hold my breath while cleaning up the pile of liquid brown.  Some of her crap found its way on my hand, and I suppressed a gag.  My hands worked quickly, wiping and throwing the soiled towels into a garbage bag destined for the green trashcan outside.  I've washed these hands about a dozen times since.
