He definitely has always had that "I'm a charming 3 year old who just did something bad but you know you can't get mad at me because I'm so cute and helpless" thing working for him. Of course, he also has the "I'm a 3 year old who will whine continuously and sulk in the corner until you give me attention" thing too. Unfortunately for me, both of these used to work on me. Now the first makes me want to puke and the second makes me think that infanticide might be a good option if the infant who behaves that way is 43.
I wonder how much of his poses stem from the fact that he's pretty. He reminds me a bit of a spoiled petulant Lord Alfred in that Oscar Wilde movie. Not only the toddler-esque supposed-to-be roguish charm, but something almost ... effeminate. *ponders elusive taste on her tongue*
You're absolutely sure he's been playing for the right team all those years? I'm only half joking.
