What does the "B.S." in B.S. Pulley, the 40's and 50's character actor, stand for?

This was a hard one to track down, and I'm not 100% on the answer. From what I was able to dig up, B.S. Pully (he sometimes used Pulley) was a comedian, as well as an actor. His ribald humor was considered for adults only at the time. The B.S. stands for bull *(explitive). He once worked with a partner on his comedy act named H.S. Gump, the H.S. stood for horse *(same explitive). Hope this helps.

B.S. stands for Bull Shit. H.S. stands for Horse Shit. He made one record album (had canned laughter throughout) called "Fairy Tales" which is hilarious. When filming movies (like "Guys and Dolls" in which he played "Big Julie", the gambler from Chicago who wanted to "shoot craps"), they called him "One-Take Pulley" because he had a photographic memory and would nail his part in one take. When he traveled, he didn't need a phone book to call whomever he knew in any city because he had all the numbers in his head. His nephew is my best friend and he told me all this.

When asked, Pulley said that BS stood for Bernard Shaw.

Gump was his partner, sent a telegram from the
West coast to Pulley in NY asking for money.

Pulley replied, on a postcard, "Enclosed you will
find the money you requested."

Pulley's real name was Morris Lerman.

H.S Gump's name was "Chester" Lerner. He had a twin brother named Harry, who was my grandfather.
