Huckleberry Hound Meets Mister Muggles

[Caius Marcius]

No: HPFGUIDX 22702

We all know that there is a certain author out there who claims that 
the entire HP narrative was plagarized from her by JKR because she 
supposedly was the first to use the term "Muggles." 

For no discernable reason, I had a flashback the other day to a 
cartoon I viewed on several occasions during my childhood.  
Unfortunately, an extensive Web search shows that the Net has yet to 
evolve to the state that it includes a plot synopsis of all the Hanna-
Barbera cartoon episodes.  My research suggests that the cartoon was 
titled "Postman Panic," with Huckleberry Hound as the protagonist (it 
would have been released between 1958-1962). In this particular 
vignette, Mr. Hound took on the role of a mail carrier entrusted to 
deliver a vital message to one Mr. Muggles.  However, a militant 
watch dog (the cartoon fails to address why some canines have become 
gifted with upright posture and articulate speech while others remain 
mired in mere mutt-hood) thwarts HH's every attempt to deliver the 
letter.  At the end, we learn that Mr. Muggles and the fierce 
watchdog are one and the same, and that the message is a singing 
telegram wishing Mr. M a happy birthday.

Questions

Are Hanna-Barbera cartoons viewed at all in Britain? (in terms of 
animation quality, they are absolutely hideous, but they remain 
popular stateside)

Might JKR and She-Who-I-Won't-Bother-Looking-Up-So-I-Can-Name-Her 
have both derived the name Muggles from this Huckleberry Hound 
cartoon? Does anyone sing "My Darling Clementine" in either of their 
narratives?
