Swollen balls?

Only 20odd overs into the 2nd innings on Monday morning England manage to get the non-swinging ball swapped for another one, apparently on the ground that it's swollen and wet. This was then conspired to by Steve Bucknor with his little metal ring thing. Pansies. You try playing with a ball 10 minutes after taking guard against my dog Wicket...

I didn't have a cantaloupe melon handy for comparison...
