I didn’t get a chance to watch the episode yet, so I’m a little unsure of the context, but here is proof of the Phillie Phanatic’s triumphant(?) debut on The Simpsons where he appears to be greeting a group of nuns who are getting off of tiny boats:

Matt P over at The Level has video posted from the ep if you’re into that sorta thing.

UPDATE: Now, thanks to commenter Robert, I have absolutely no interest in actually watching the episode. Instead, I’ll just choose to believe it revolved around the story told by Chamo during his Phillie Phanatic roast:

I want to share a story with you about my good friend — and our guest of honor tonight — the Phillie Phanatic.

A couple of years ago, the Phanatic and I were up in Alaska hiding from his bookie. One day, we got completely shitfaced because when you’re in Alaska, it seems like the only sensible thing to do.

We staggered up to a convent nearby, and I started whaling on the front door. Sister Mary Whats-her-face answered, and the first thing I said was, “Do you have any midget nuns around here?”

She said, “No, we don’t.”

I turned to the Phanatic and said, “See? You fucked a penguin.”
