Scooby-Doo!: Behind the Scenes - Season 1 Episode 8 Those Meddling Kids, Together Again

After solving more than two hundred mysteries together, Daphne says the one thing she's learned is to avoid "paintings that blink" with Velma recalling that the all the bad guys they deal with hang portraits on their walls, with not one haunted house they've visited having had a landscape. At Fred's suggestion they recall the case from Never Ape an Ape Man, although they claim that Fred couldn't get the Ape Man's "mask" off because it was a real gorilla. Velma sums up what they do as "find a mystery, run around, trap a bad guy [and] rip his mask off". Fred says they have fun doing it, at which point Scooby scares Shaggy by putting on a gorilla mask. Fred proceeds to put a hand on each of their shoulders, proclaiming, "I love you guys." Velma is quick to shut him down however, firing back a snarky, "Knock it off."
