I thought that somewhere when Dave and Dirk are talking to each other, Dave mentioned that Bro filmed him for porn, was this true or do I have my facts wrong? And if it is true, would you mind terribly citing where it was? Thank you in advance!!!

Bro didn’t exactly film Dave for porn. Bro has cameras set up all over the place and Dave may or may not have shown up as an accessory in some of his puppet stuff. Which is super weird fetish stuff so not necessarily explicate such as the time Dave shredded a puppet in the blender: 

 It seems you may have just been an unwitting accessory to some sort of grisly puppet snuff film.
