A surprising number of people like D&D. And because this is the Internet, people make memes of things they like. ML likes D&D too, so he probably browses places where people post and updoot those memes. He saves those memes for his own later usage. Maybe he even makes memes of his own; I don’t know.
Enter this thread, where people are allowed to post what-the-fuck-ever (modulo rule #0). He posts what he’s got, and what’s near and dear to his heart: D&D memes.
Honestly, it’s a question with a pretty straightforward answer.
