Tidus Fantasy X is exactly what it says on the tin, e.g. It took until 2016 for some uber-dweeb to take the joke to its natural conclusion and create a modified version of FFX which has Nobuo Uematsu and co.'s original score altered significantly with sampled, manipulated Tidus Laughs in the place of pianos, horns and other typically melodic instruments.
The Tidus Laugh has since been inserted by fans into numerous sitcoms, uniting nerds across the world through the appreciation of iffy voice acting (Respect to Tidus' voice actor James Arnold Taylor, though, as he's still making money off voicing Obi-Wan Kenobi in literally every single Star Wars game and TV show).
