If you grew up watching Scooby-Doo, The Jetsons, Yogi Bear, Jonny Quest, Wacky Races, or The Smurfs, chances are you already knew Don Messick—you just didn't know his name. One of animation's most talented and prolific voice actors, Messick brought an astonishing variety of characters to life, including Scooby-Doo, Astro, Boo-Boo Bear, Ranger Smith, Muttley, Dr. Benton Quest, Papa Smurf, and Azrael.

 

Of course, no Psycho Bob Says episode would be complete without a healthy dose of feline commentary. Bob is particularly impressed that the man who gave us Scooby-Doo also voiced Azrael, Gargamel's cat, proving once again that cats have excellent taste in entertainment.
