Do you suppose it's true, that St. Patrick was a parselmouth, and his muggle friends never knew?

The line playfully fuses Irish hagiographic legend with the fantasy lexicon of Harry Potter. St. Patrick is traditionally credited with driving the snakes out of Ireland; recasting him as a “parselmouth” (someone who can speak to snakes) reframes the miracle as a wizarding skill rather than divine intervention. The mention of “muggle friends” adds a comic angle about hidden identities and the gap between ordinary perception and secret power. Beneath the joke is a gentle commentary on how myths can be reinterpreted through contemporary pop culture, and how modern fandom language can serve as a new shorthand for explaining (or deflating) old stories.
