"Dum, dum, dum, DUM!!" -Scooby-Dum's catchphrase.
Scooby-Dum (voiced by Daws Butler) is Scooby-Doo's cousin and an ocassional member of Mystery Inc.
- Whenever Scooby-Dum hears the word "Clue", he would invariably pull out a magnifying glass and, intoning the opening four notes of Beethoven's Fifth Symphony, chant, "Dum, dum, dum, DUM!", even after a mystery is solved.
