Hello Gymglish, I have been working my English with your method since 2010 and roughly I am very pleased about it. You're doing a really great job! Especially, humour and funny situations are very powerful to reduce feeling of working during our lessons. However, respect is important, particularly respect of religious belief. So, I would thank you very much if you didn't laugh or speak about Pope, Christians, Rabbi, Jews, Mohammed or Imam. I do think there are enough funny situations in working and day-to-day environment observations. To sum up: make sure you don't hurt personal belief but continue to mix fun and work and thanks again for the great job you are doing.
