Time travel was a popular science fiction plot device in the 50's & 60's, and still is from time to time today. One of the backup features on King Leonardo & His Short Subjects was Tooter Turtle, a well meaning sort who kept bumbling into one misadventure after another, relying on Mr. Wizard, a lizard (Sandy Becker) to bail him out of trouble.
Here's "Tailspin Tooter (Plane Failure)", a parody of the comic strip, Tailspin Tommy.
I remember seeing some of these shorts in syndication in the late 70's & early 80's, and all I could figure was that Tooter was perpetuating the stereotype that turtles, because they are slow afoot normally, were also slow-witted. As I noted above, Tooter meant well, but his lack of intellect was his one weakness, and that actually hindered him. A reboot today might upgrade the ol' noggin, though......
