So, Master Doodle ran into the bedroom (a sure sign he intends to poop in his underwear, as he’s in the midst of potty training), and when Mrs. Smith went to open the door, it was locked.  Uh-oh.  Doodle must have heard the handle jingle because he yelled out “Not by the hair on my chinny-chin-chin!”  Mrs. Smith then played along with the Three Little Pigs child who refused to open the door to the Wolf…  in other words, he refused to allow Mrs. Smith into the room until he’d done his nefarious deed.  Ick.

At least there was some humor in the situation to diffuse the otherwise unpleasant and messy experience.
