I used to make fun of dlb and the duckfaces but after seeing her and her husband in a few interviews honestly they come across as cool hard working people and I have alot of respect for what they do.Rob seems to be a workhorse andf has mustiple businesses under one roof, why hate on them so much, they promote working out for people who 20 years ago would never dream of picking up weight training(hot chicks)
