The episode: “The Horrors of Spider Island,” ep. 1011
The riff: Called out invitingly by Mike as our high pants-wearing “hero” stumbles through the brush toward a large spider-like monster that is lying in wait.
The explanation: Mike is paraphrasing a famous English poem by Mary Howitt called “The Spider and the Fly” that was first published in 1829. It’s about a spider trying to trick a fly to enter its web through seduction and flattery, telling the fly how wonderful it all is. The poem was often taught to children as a lesson about guarding against fraudulent and dangerous tricksters. You can read the full text here.
Novelty factor: I don’t remember ever having learned this one in school, which is too bad.
