Come on BTF. Surely an aide should have had a quiet word about it. It's not like it's a permanent deformity, it's an action he does. Spastics do things like that (window licking etc). Maybe no-one has mentioned it because they feared a Brown tantrum. That said he was obviously told to smile more and the British public cringed at that stunt, so maybe they've decided to just run with his spazzy mouth thing.
