I always disliked TB's grin (well, I'm entitled to: I'm English). But I finally realised it's not deliberate, he can't help looking like that.I think maybe he fell (or was he pushed?) in a vat of acid, like Jack Nicholson in Batman. I have this lurking fear he might turn into Jack Torrance from The Shining ... it may already have happened ...

Cherie (Mrs Blair) as a strange grin, too: her lips are closer in the middle than at the ends; she looks like she's forcing a smile to stop anyone seeing she's crying. Maybe she's seen hs chopper...?
