i think Corey Graves said on a recent show that he learnt his anatomy from Heenan
my favourite moment of mine has to be the Rumble 92 when he was Flairs manager, he was shitting bricks for the duration. He was also a big part of the first ever wrestling match that i watched on a Silvervision production, Rude vs Piper in a cage match - he threw some brass knucks into the equation
lets not forget his time in WCW too, was crucial i think to their immediate upturn
