DC, it was only a joke based on the amount of energy expended on rolling a cigarette rather than fishing one out of a packet - about as much
exercise (assumed) that most pro golfers of that era took.
I know...I met Sam on a few occaisions. Best word I can use to describe him, "crotchety". He played in a pro am at Seaview CC when I worked there back in 80s. I talked with after the round and he was pissed off that he got "a bunch of hacks" on his team.
