If you take up psychology and wish to see psychological phenomena like cognitive dissonance, doubling down, rationalizing wrongs, group-think, etc then JWs are a gold mine of case studies for psychology majors.
Maybe you can say something like: "Anyone here studying psychology? Show by raise of hand. Go to the nearest kingdom hall! Your psychology professor will love you!"
"Anybody here studying literature and having trouble understanding George Orwell's 1984? Go to the nearest kingdom hall! Your literature professor will start asking you for answers!"
Peter Boghossian once said at one of his talks words to the effect that he found Jehovah's Witnesses to a particularly hard nut to crack VIA the street epistemology method. You can find the clip on youtube then you can work it into your routine like this:
"Peter Boghossian once said that Jehovah's Witnesses are particularly invulnerable to being reached with the socratic method of street epistemology. Folks, these are special people! What makes them so special? How is that they everyone else can be reached but they can't? What powerful methods of indoctrination are they being subjected to? [Then you play a short video clip of Steven Lett saying something ridiculous with his face contorting all over the place]"
