Since the Doubtful Guest looks a bit like a penguin, I'm particularly enamored.

Now I long for a doubtful guest costume. Building the beak/nose would be the only tricky part, if one already happens to have a Doctor Who-like bizarrely long scarf, as who doesn't? Excellent costume for anyone who feels socially awkward, ie. at least half of humanity. Plus I'm short.
I never actually noticed the son growing up before this time, I don't think.
