Sitting this morning playing Webkinz with Jack on the computer...
Me: "Jack, you so need a bath tonight. And I need to clip your nails."
Me: "Because you are filthy. Look at your fingers. You can see dirt under your nails."
Jack: "You know how they got dirty?"
Me: "No, how?"
Jack: "Because sometimes I stick my fingers up my bum bum and get poop on them."
Me (pushing Jack off my chair): "Eeeww! That is disgusting. Go wash your hands immediately!"
