Oscar’s had a sense of humor since he was an infant – really.  He loves nonsense and playing hide and seek (read: me running out of his direct line of vision and then peeking around the corner to his delight) is a new favorite that goes on all day long in our house.  I came across this little house which I know he’d love – I can see it now; he’s inside and I’m ducking outside below the window.  Hilarious, I know (I guess you’d have to be there).
