In the Fireball XL5 episode "Drama at Space City", Jonathan, the son of General Zero said than Zoonie the lazoon is a tootie in this clip. https://youtu.be/b74YvjY1s3g?t=4m48s Or in "Faster then light" General Zero and Lt. Ninety mentionned then the guy at the Space station is a real tootie. https://youtu.be/mOD7r0YP6ko?t=2m38s
I couldn't resist to imagine if what Gerry Anderson had continued to use that slang word tootie for Stingray, Thunderbirds and even Captain Scarlet? Could we imagine Commander Shore saying "Tempest, stop being stubborn like a tootie" or Jeff Tracy saying "Boys, stop acting like tooties" or even a random Mysteronized guy saying to Captain Scarlet and Captain Blue "Don't do the tootie, you lost Earthmen".
It might be a blessing in disguise for Butch Hartman, producer of the Fairly Oddparents then the word "Tootie" hadn't caught as a slang and wasn't used in Thunderbirds, Stingray and Captain Scarlet. He's lucky to not see a random episode of Fireball XL5 using that word.
