Don't underestimate him!
One of my favorite things to do is to "eavesdrop" on the conversations that Josh has with himself, his "boys" (the stuffed animals he surrounds himself with) or the television. As an only child, he's had develop his own ways of entertaining himself, and he's a pro at it by now.
Every now and then I'll realize that I've heard him say the same thing before. There's one phrase that he keeps repeating on a regular basis "it's a BABY talking!" It made me wonder what the heck was going on so I decided to look into it. Turns out, he's talking to a commercial.
