The basis for this episode and the opening quote come from "The Queen Bee."
Doug is wearing a shirt that has black and yellow lines on gray and white-ish base. His cell phone has a black-and-yellow shell. The queen is dressed all in black and yellow. All references to the colors of bees.
This is, ironically, the first episode in the series "based" (however loosely) on a story originally collected and codified by the Brothers Grimm (while they collected and wrote variations on "Little Red Riding Hood" and "Goldilocks and the Three Bears," their versions were not the first). The Grimm's story "The Queen Bee" is of a kind prince who saves a kingdom through simple acts of kindness (stopping his older brothers from destroying a beehive, for instance) that earn the gratitude of the affected animals who later assist him in otherwise impossible tasks to break a curse.
"Meli" and variations of it are Latin roots referring to honey and by extension bees.
"Mellischwuler" (leader of the mellifer) comes from the Latin "mellis," meaning "honey," and the German "schwuler," meaning a gay man, likely taken from a mistranslation involving the slang term "queen." The German word for "royal female ruler" ("queen") would be "königin;" the Latin would be "reginae."
