Yakko, Wakko and Dot's cameo in the Spring Break special.
Yakko, Wakko and Dot Warner (also known as "The Warner Brothers (and the Warner Sister)", "The Warner Siblings", or just simply "The Warners") are the three main characters from the Warner Bros. animated series Animaniacs. They are a trio of cartoon characters of unknown species (Tom Ruegger stated in an interview that their species is "Cartoonus characterus"). Yakko is the tall, talkative one who is a big-time smart aleck; Wakko is the absurd one with a large appetite; and Dot is the cute one.
Although Tiny Toon Adventures had ended by the time Animaniacs premiered, Yakko, Wakko and Dot made a very brief cameo in the Tiny Toons Spring Break Special. At the annual Easter Egg hunt at the White House, they are briefly seen running while carrying a big green egg, pursued as always by Ralph the Guard.
