"Pus-finger... he's the man with the septic touch!"
Poor Norris, his thumb has ballooned with an infection which is painful, pus-ridden and has kept him (and thus us) awake for much of the night. It burst in the bath shortly after this photo was taken, spilling a quite extraordinary amount of stinking pus into the water. The antibiotics he's had seem to be calming the rest of it down now. He'll be glad when its healed up, not just because of the physical discomfort, but because he'll be spared other members of the family doing their Shirley-Bassey Bond-theme re-hash while waving their fingers about!
