[[WMG: The black cats are all Butch from WesternAnimation/TomAndJerry.]]
The cats in "The Cat that Hated People," "Bad Luck Blackie," "Ventriloquist Cat" and "The Cuckoo Clock" are all black just like Butch.

[[WMG: "Sgt. [=McPoodle=]" and "Dan Magoo" are just characters that are played by Droopy.]]
It's a possibility.
** They could also be two of his dozens of body doubles.

[[WMG: Spike is the same Spike as the one in WesternAnimation/TomAndJerry.]]
After all, they look the same.
* Tex, Joe and Bill did us no favors here. Tom and Jerry have both a Spike (the grey bulldog) and a Butch (the black cat). Tex's yellowy irish dog has been called Spike or Butch depending on the cartoon. If anybody seriously needs a rename in the modern era, it's probably that guy especially when they want to use him at the same time as Tom and Jerry's Butch and Spike.

[[WMG: The guy who tells the "literal" story in "Symphony in Slang" has a name; it's just not mentioned.]]
The Big Cartoon Database identifies him as "John" so as to match "John and Mary" in some of Tex's other cartoons.

[[WMG: George and Junior did not commit suicide at the end of "Half-Pint Pygmy" and are the hunters in "Lucky Ducky."]]
The hunters bear a strange resemblance to them...

[[WMG: Screwy Squirrel dated a young Slappy Squirrel.]]
Also included on the ''WesternAnimation/{{Animaniacs}}'' WMG page. After Screwy's death at the hands of Lonesome Lenny, Slappy became bitter and cynical, never overcoming the grief.

[[WMG: Conker the Squirrel of ''VideoGame/ConkersBadFurDay'' was the illegitimate lovechild of Screwy and Slappy.]]
Conker is basically a more modern version of Screwy, with the same red fur color.

[[WMG: B.O. Skunk and the female skunk he meets at the end of ''Little Tinker'' are Pepe le Pew's parents.]]
Pepe resorts to even more aggressive methods for finding love, perhaps after having been coached by his "father" at an early age. And the French accent is fake (B.O Skunk himself puts on a fake French accent at one point).
