As the father of three sons, I think I'm pretty well versed on gross. I've seen some really nasty injuries, cuts, breaks, you name it, some gross stuff.
This show does not discriminate, they have all kinds of feet. Bloated, swollen, cracking and crusting feet, seriously every type of foot, it's on the show. There is even a toenail so yellow and brown that the patient looks away. Gross!
