Quite right, I can only recall Vettori really losing his composure twice in the 18 years he's played internationals come to think of it;
1) His reaction when NZ got over the line in that infamous 2008 ODI in Eng when Paul Collingwood displayed poor sportsmanship in not calling Elliott back from a run-out after he'd collided with the bowler. I'll never forget Vettori's angry fist-pumping from the balcony when NZ got over the line off the last delivery.. It was so un-Vettori like
2) His reaction as he crossed paths with Andy Moles after being dismissed in the 2009 T20 vs. Pakistan after Umar Gul was getting the ball reversing after about 8 overs. Not sure if anyone remembers that, but you could hear Vettori uttering something like "That's BS, I want a **** official complaint laid about this ***" as he passed Moles on the way in..
