• Contrary to what Luke and Evan claim at the tail end of this episode, Shaggy does actually catch and carry Scooby after he's been tossed in the air by Skipper the dolphin.

EPISODE 5 - "Scooby Dude"
A Pup Named Scooby-Doo
Season 1, Episode 9

Have you ever wanted to take a peek at what your favourite gang of colourful misfits were like when they were children? Then you're going to love Young Sheldon, which focuses on The Big Bang Theory breakout character's upbringing, airing this fall only on CBS! You're also probably going to be pretty into A Pup Named Scooby-Doo.

Much like the gang heading out to the beach to enjoy the wind and waves, sun and surf, Evan and Luke came to this episode without expecting the very serious, real life issues that awaited them. This episode manages to be the preachiest to date, while also featuring one of the co-hosts descending to the absolute lowest form of humour (as well as a [too] thorough discussion of childhood animated crushes). 

  • Luke likens Scooby's paws to looking like Hobbes' paw pads in his earliest appearances, before cartoonist Bill Watterson stopped drawing them in. In retrospect, Evan realizes that they're much more like Morbius's palms in the 90's Spider-Man animated series, where due to censorship the character was not allowed to use his fangs for vampiric purposes.
  • Luke also says that Velma is "kinda in chibi style". That refers to a "super deformed" art style where anime or manga characters are depicted in an exaggerated fashion with oversized heads. 
  • There are obviously more parallels between Norville "Shaggy" Rogers and Forsythe Pendleton "Jughead" Jones III besides narrating their respective TV shows, with the most obvious being that they both own dogs who share their gluttonous appetites.
  • There's a lot of talk about tropes in this episode, Red Herring notwithstanding. To elaborate on at least one of them, Aunt Thelma's unrealistic diction is a fine example of "Sesquipedalian Loquaciousness", or using SAT vocab words to sound smart.
  • Evan once read a Choose Your Own Adventure book simply titled "Supercomputer", which was also written prior to the invention of the internet but still featured a machine that could access any and all of the world's information.
  • To let Wikipedia do the heavy lifting, "a very special episode" is "an episode of a sitcom or drama series which deals with a difficult or controversial social issue," in this case being DRUGS.
