i noticed that - he's been cracking loads of little asm jokes lately. i think that anglegrindergate taught him a life lesson, and since then he's been much more laid back and easy going with his peers. it's like he knows that life is fine, but you're only ever one small mishap away from crank-related savagery.

That sort of reads like a teacher report.
