Back over 40 yrs ago, the gym had only 1 public pay phone.
A few times a week, some schmoe would call the gym .
They would answer the phone and a breathless, shaky voice would ask;
" Is this really Gold's gym?" When that was confirmed he would usually ask the following:
" Are you are bodybuilder? "
" Are you too busy working out to talk right now?"
" Would you mind if I came over to watch you workout?"
" Is Arnold there? "
" How big are your arms? "
" Do you have a big dick ?"
They would often point to the phone, cover his end and yell out to the gym crowd ;
" Looks like we have a heavy breather."

Some of the bodybuilders , would run to the phone, giggling like little kids.
A few would even do their best Arnold voice to get the guy going.
The others would often gather around the phone, struggling not to laugh loudly and suggest things to say.
