Watch the last seasons where you not only get Laverne and Carrie Fisher (Shirley had left by that point) becoming Hugh Hefner's bunny girls -- MKULTRA and CIA "ownership" symbolism.

Same season it's set mid 60s, and they have an episode with a Paul McCartney double mixup plot, referencing Paul's murder and replacement in 1966.

Laverne's actress was married to Rob Reiner.

The further feminisation of Lenny and Squiggy came in an episode of The Nanny in the 90s, where a character played by David Lander and implied to be Squiggy, is the gay landlord and makes a sex joke about "my partner Leonard".

Fran Drescher was also part of that extended circle, having been in Spinal Tap with Reiner.

They made a few attempts at a spin off, one being Lenny and Squiggy Join the Army, which failed and got retooled into the Laverne and Shirley cartoon where they join The Army for some reason.

To me, it looks like the CIA agents in the industry, were tasked with pushing military engagement, at the same time they were pushing peace propaganda of the "don't attack the Communists " variety.
