It is revealed that the Warner siblings, after being locked away in the water tower in 1934, have to be let out every 11 years so the tower can be debugged. In 1945, they visited the Geneva Convention with FDR, Winston Churchill, and Joseph Stalin; in 1966, they masqueraded themselves as a Beatle-esque rock band on the Ed Sullivan show; in 1977 they taught Travolta the dance moves he would use in Saturday Night Fever and Grease; in 1989, they helped the people of East and West Germany by giving them hammers and picks so that they could break the Berlin Wall down. They were let out of their tower in 1994 so they could attend their 65th anniversery special.
There actually was a cartoon character named Buddy who, in the mid 1930s, had his own series of cartoon shorts at Warner Bros. Unfortunately, this character was so bland and so boring that Warner Bros. quickly sought to replace him. After Buddy was fired WB released a cartoon called "I Haven't Got A Hat" that starred a variety of cartoon characters, among them Porky Pig and Beans the Cat. The cartoon was to let the public decide who should be the next star, and Beans was picked with Porky as his sidekick. However after a few cartoons Porky proved to be more popular, and so Beans was fired and Porky was made the star. On a side note Buddy was a replacement of the more popular Bosko, who stopped being a WB star when his creators Harman and Ising left the studio in 1933.
