Blending wit, slapstick and pop culture references, the variety show “Animaniacs” features a large cast of characters, whose predominant personalities are the Warner brothers, Yakko and Wakko, and their sister, Dot — three inseparable siblings — who have a great time creating havoc and mayhem in the lives of everyone they meet. The series, which originally ran from 1993 thru 1998, also features a number of comedic educational segments, often in musical form.
