The first season of Total Drama is a parody of reality shows, while the second and third also parodies of films and musicals, respectively. So, it'd be impossible for them not to have their very own Shout-Out page.
World Tour has many towards The Amazing Race, the most obvious being the world travel aspect of the show, and that almost every episode has a challenge that include racing to a "finish line".
The episode title "The Am-AH-zon Race" is a direct reference to the show title.
In "Walk Like an Egyptian - Part 1", racers are given the option of going over or under a pyramid, presented in the exact same way Detours are given on the Race.
In several later episodes, team are given tasks for only one team member to perform, which mirrors Roadblock on the Race.
Both challenges from "Walk Like an Egyptian - Part 2" (the camel race and boat building) were lifted from different seasons of the Race.
The statue assembly challenge from "Can't Help Falling In Louvre" was originally a Roadblock on Season 9 of the Race.
In "Niagara Brawls", players are split into teams of two. Later, they're tasked with crossing a high wire over Niagara Falls, another frequent Race challenge.
Owen's jump on the first challenge of season one is a reference to Survivor: The Australian Outback, when one contestant overcame his fear of heights to jump off a cliff, giving his tribe the victory.
Another shout out to Survivor happened with Alejandro being turned into a ratings machine - Survivor had one of those, his name was Russel Hantz - and if you watched Samoa, you'd think the cast consists of just Russell Hantz and nobody else. And in Heroes vs. Villains, it consisted of Russell, Parvati, and Boston Rob.
An episode was called "Phobia Factor", in tribute to "Fear Factor"
"Wawanakwa Gone Wild!" is a reference to "E! gone Wild" shows.
Team Victory and their abysmal record is likely a reference to the infamous Ulong tribe in Survivor.
The second episode of Revenge has a challenge reminiscent of Wipeout.
Since Total Drama Action takes place in a film studio, pretty much everything in it makes reference to movies. Not to mention that '''A LOT''' of episodes are named after movies (even some from other seasons):
