That story about Johns hitting the uprights reminds me that Wally did something similar after the final siren in a Brisbane club game, except it wasn't a grubber. The opposition wasn't sure if it was a bomb or field goal attempt and they just stood and watched as it bounced back into the arms of one of Wally's team mates, who strolled over for the winning try. Maybe Johns saw that one also and practised the move.
