Remember when the "name a more iconic duo" challenge was a thing?
Well, the newest version of that comes on the heels of Marvel's highly-anticipated film, "Avengers: Infinity War," in theaters next month.
People are taking to Twitter to take on Marvel's statement that its latest superhero film is "the most ambitious crossover event in history."
Animation director, Butch Hartman, tweeted the television crossover film trilogy set between the universes of The Adventures of Jimmy Neutron: Boy Genius and his own show, "Fairly OddParents."
People have been offering up their own ambitious crossovers, such as this one from Disney when the network mashed its top three sitcoms together into one episode.
Or that time the Ninja Turtles met up with the Power Rangers. (!!!?!?!)
And of course there's this gem when "Friends" cast mates Jennifer Aniston and Matthew Perry teamed up with Microsoft Windows, because the 90s was way too good to us.
