Was the original voice of "Buster Bunny" on
Tiny Toon Adventures (1990). He reportedly quit after learning that he was not going to receive a role
on the upcoming series,
एनिमेनियाक्स (1993), despite having been the lead on "Tiny Toons" while other actors form the series, such as
Rob Paulsen,
Maurice LaMarche and
Tress MacNeille, were being given roles on
एनिमेनियाक्स (1993), and was further angry when he learned that a prominent role (Wacko) was given to
Jess Harnell, who was a relative newcomer to voice acting at the time while Adler himself had much more experience. Adler was replaced by
John Kassir, better known as the voice of the "Crypt Keeper" on
Tales from the Crypt (1989).
