Our fearless heroine Debbie Brown is out there gettin' it done. She is our Muse, our guiding light, our grand metaphor, and she is not alone. All of us here at Team Shredder are in fact doing the parasite purge together, including Sheldon le chat. And I have to say that it's Debbie who is truly the eye of the tiger.
Sure, others have done the purge...
"Yeah, and then she sounded like shit." -Dick Blew
The point being that the purge might othewise feel like a scary, risky cliff dive into the abyss of the unknown, without the experience and calm groundedness that Debbie Brown is famous for. Please refer to "Debbie's Barium Swallow" in The New Fuck You for further data.
