The tradition of putting different adjectives in front of the Celtic Guardian's name reached its closest sound-alike in this episode, with the Agnostic Celtic Guardian.

Yugi calls Kuroboh the Annoying Kuriboh, a reference to the Annoying Orange.
Duke Devlin says he's losing his mojo, a reference to Austin Powers.
Tristan confuses an axe, a medieval weapon, with Axe, a line of male grooming products.
Téa refers disparagingly to the films of Don Bluth, who is generally considered by critics to be a brilliant animator who has directed a number of weak animated films featuring anthropomorphic animals.
When Tristan tears down the wall of the castle, he says "Here's Johnny!", a catchphrase which was used to introduce television host Johnny Carson. This catchphrase is famously referenced in The Shining by the character Jack Torrance when he tears down the door of a bathroom with an axe.
Gansley saying "It's a double rainbow!" is a reference to the viral video "Yosemitebear Mountain Giant Double Rainbow 1-8-10".
After the duel, Yami and Kuriboh converse in a manner stereotypical of the TV series Lassie. The line "Timmy got stuck down the well?" is a reference to fact that the character Timmy repeatedly became stuck in places such as abandoned mine shafts, rivers, and quicksand, but conspicuously, never in a well.
