The idea for San Pedro Beach Bums started with a producer visiting Walker's Cafe in San Pedro (near Point Fermin Park). There's a particular and rich history to San Pedro humor which can be found there. Unfortunately, Aaron Spelling chose to hire the usual bevy of writers and missed the point of the humor.
It could have been a good show with Mexican, Slav, and/or Italian (hyphen American) writers. Look, I have quite a few Jewish friends... and that works well for "Three's Company" and the like. The humor at Walker's is nothing like that.
