Hah, I went to check and I can't believe somehow the Hysterical Parents' Association or whoever does the warnings managed to make a list as long for sex and nudity as violence and gore. I mean seriously? There's about 10000 more of the latter on the show!
I did find the sex and nudity warnings amusing though.
there is a prolonged scene in which Skyler gives Walt a pitiful handjob
Marie makes a bet whether Hank will get a boner by giving him a hand job
Hank was almost caught watching porn on television
^^What is this show, a porno?!
Anyways, yeah, those ratings on IMDb aren't always correct. I mean according to IMDb Mad Max 2 is
banned
in my country, but I remember it aired on TV before the release of Mad Max: Fury Road and also I'm pretty sure it's on my Netflix lol. I investigated a bit and couldn't find any notion of the film ever being banned here, let alone right now.
Do you even know what honor is?

A lot of things IMDB have on the site are incorrect such as cough ratings cough
