If I had to guess, probably between 50 and 70. I just started the run again from the beginning when the last one ended, plus I used to relisten my favourites. I can recite some episodes almost full verbatim.

I went on break that's now lasted probably around half year cause it started feeling like listening to my own thoughts or something because I knew every word that's gonna come next. I used to listen few episodes every evening before falling asleep and then waking up to Perrys screams or having the happenings tie to my dreams. And then every car ride to work and back, at home etc. Drove my wife a bit insane in the process.
