Animaniacs (1993) s03e09
Titre original : "The Sound of Warners / Yabba Dabba Boo"
(1.) In a musical parody of The Sound of Music, Mr. Plotz hires Prunella Flundergust (a parody of Maria von Trappe), a nanny who unknowingly gives the Warners a hard time with her constant singing and motherly personality. Since they cannot do anything to her unless she insults them, they try ruining her songs. When that does not work, they enlist someone who is not bound by the "Don't Provoke unless Provoked" code, namely Slappy Squirrel.
(2.) Chicken Boo attends a table read for The Flintstones movie.
