This comic serves two purposes:
1. The author shows that, while being a child prodigy, was not a complete dork after all, he was cool and clever, because he avoided reading books for school assignments and instead watched the tv version.
2. Some obscure reference to some shit american show from the 90s. A lot of the viewers might have seen it too. This is the ultimate confirmation that they are very much like the author, a genius and cyber poet.
The joke is that fifty shades of grade would not be on a family-friendly tv show because it is an erotic novel.
It was brought to my attention that it is also sexist. I guess I do not even notice how much the author hates women any more.
