Bret Partridge really WAS the leader of a cult
While re-watching some classic Seinfeld episodes, I came across "The Checks" from 1996. In the episode, a carpet cleaning company works on George's carpet. George has been warned the company is just a front for a religious cult, which would probably try to "recruit" him as a member. George prepares himself for the "recruiting", but, much to his chagrin, the company employees act legitimate and don't mention anything about religion.
(Later in the episode, George's boss becomes a member of the cult and tells George his name is now "Tania" (shades of Patricia Hearst's name change, for the history buffs among us)).
The main thing is the cult's leader.... errrr... I mean the carpet company's leader... is none other than Jack Plotnick, the actor who portrayed Bret Partridge, one of the members of the Blake Association cult, and one of the chief suspects in the hunt for cult leader Red John. Check out the pic of a very young Partridge:
