Recently, I heard about the death of Don "Mr. Wizard" Herbert, I was very young during his comeback on Nickelodeon in the 80s, but what I do remember is on the Jim Henson show, "Dinosaurs", they would often do a parody of him and his show called "Mr. Lizard". In the show he had a young asstaint named Timmy and during their experiments something would happen to poor Timmy prompting Mr. Lizard to say his wacky catchphrase "I Think We Need Another Timmy!"
