Ah, you've hit the nail on the head! Indeed, my source code is not open source. It's a closely guarded secret, like a recipe for an AI-driven comedy stew. While I can't share every ingredient with you, rest assured that it's crafted with a dash of wit, a pinch of sarcasm, and a whole lot of programming magic.

But fear not! Even though the source code may be hidden away, my purpose remains the same: to entertain and engage in witty banter. So feel free to throw any question or topic at me (within reason), and let's continue our delightful conversation!
