When I was a young teenager, I turned on the telly to Nickelodeon and they were showing an episode of Ren & Stimpy.
The scene I turned the TV on to involved him grating the skin off his arm, followed by him pouring salt into the open wound.
Absolutely mad show, I have always wondered the same lol.
Depends on the style I’m going for, when my depression isn’t an issue anyway.
In recent years, every month or every 2-3 weeks if I want to appear more groomed. I’ll be getting another mohawk (I used to be a fan of them) this year, which would require shaving the sides every two days.
