Unless you're an actor, you don't get very many chances in this life to pretend to be something you're not (outside of the regular mask-wearing of being a person in so-called polite society). We get to do it on Halloween, in improv class, or if our significant other is feeling particularly freaky one night. We also get Dungeons and Dragons, a setting wherein we can transform shamelessly into other creatures with extraordinary abilities. We get to do funny voices, we get to say funny names, and if we choose to, we can wear funny costumes. It's important for your sanity as an adult.
You need outlets throughout the week or all your pent-up nerdiness will have nowhere else to go and you'll implode. Thank goodness we have DnD. And thank goodness we have DnD memes, or else we might really go crazy. Now on with them and let your freak flag fly.
