Scooby-Doo (animation)/Fridge

Fridge Brilliance

 * In Scooby Doo, while the Hex Girls perform some spectacular music for something aimed at kids, their lyrics usually seemed to be set on either Stylistic Suck or So Bad It's Good. The reason is given in Mystery Incorporated (albeit for an Alternate Continuity): . - Metal Shadow X
 * What sense does it make for monsters to actually exist in the Scooby-Doo universe, when the whole point is that monsters are always people in costumes? Because that's precisely what makes dressing up as a monster such an effective disguise.

Fridge Horror

 * Stop and think for a second of the situation from the character's points of view. They're alone and completely defenseless as they are running through the dark being chased by a shrieking psychopath wearing a mask.
 * The Episode "A Clue for Scooby-Doo". Underwater in a sunken ship, they find a dead man in a diving suit with his oxygen hose cut, so he presumably suffocated down there completely alone. What's worse, the Villian Of The Week was trying to do the same thing with Fred, Velma and Daphne, and as they still had a link to their oxygen tanks, had they remained trapped, they would have lasted quite a while before dying.
 * Cracked.com gives another disturbing take on the series as whole, with their list of "Six Classic Kids Shows Secretly Set in Nightmarish Universes" http://www.cracked.com/article_19496_6-classic-kids-shows-secretly-set-in-nightmarish-universes.html

Fridge Logic
"Shaggy: Heads we take the left side and I eat it, tails we take the right side and I eat it. Velma: How can you have heads or tails on a slice of bologna? Shaggy: Heads is the mustard side...tails is plain."
 * Why haven't they caught on that it's always Old Man Jenkins in a Rubber Suit?
 * The movies did address that, just in time for that not to be the case.
 * In Zombie Island, there is a whole montage and song about how the ghosts always turn out to be fake. Again, the real villains turn out to not be the case.
 * Another example in Scooby-Doo! The Mystery Begins: We finally figure out that Scooby Snacks are made with water, flour, eggs, cocoa and dog kibble "for texture". Chocolate is poisonous to dogs. Why is Scooby not dead?
 * Because chocolate isn't THAT poisonous to them.
 * Actually, considering that the main reason why dogs die from chocolate is because of their lower tolerance for stimulants than humans, essentially making chocolate dog cocaine, this explains a lot.
 * And, considering how Scooby Snacks seem to have the same effect on Shaggy as they do on Scooby, well... Squick.
 * Further lampshaded in the pilot for Mystery Inc., when Velma is giving a tour of her parents' museum, when she drops the bomb on her excited charges that not one of the original series' mysteries was an actual supernatural shenanigan; her parents come along to shut her up real quick after that. All of the gang's parents share the sentiment-the mysteries of the original series have been retconned to have all happened in the gang's hometown of Crystal Cove, and the supposedly supernatural activity ensures a brisk tourist trade; they don't want their kids to keep solving mysteries because they enjoy being employed.
 * Zigzagged in "Haunted House Hang-Up": To determine which side of a fork in the road the gang should take, Shaggy chooses to flip a slice of bologna:


 * In a scene from "Kooky Space Kook", Shaggy and Scooby lock themselves in a cabin at the airfield, and Scooby tosses the key out the window. The space freak manages to get in by opening the door from the other side. Our heroes run to escape through the locked door but can't get out because Scooby threw the key out. They jump out of the window, grab the key, jump back into the cabin, then unlock the door and escape.
 * "Mine Your Own Business" has a more perplexing bit. Having found the combination to the hotel safe, Fred offers to read it as Shaggy manipulates the dial. Shaggy proceeds to turn the dial and Fred isn't saying anything except at the end:

"Fred: I have the combination...just turn the handle to the left. Shaggy: Well, why didn't you say so?"
