Aren’t Scooby & Co generally invited to help solve the mystery? It could also be argued that Scooby is indeed a service animal… more than Shaggy is, at any rate. And I’m sure they have a fireworks license.
There are, of course, popular sentiments that Shaggy was a stoner, and that the Scooby Snacks induced drug-like euphoria. I say this somewhat tongue-in-cheek, but a friend once told me that, in the earliest episodes, the opening credits included the group emerging from the Mystery Van amidst a cloud of smoke. And that the backstory was that they were on their way to Woodstock. Is any of that true?
Hmmm…I could go for some Road Runner ankle right about now.
The better question is why doesn’t Wile E Coyote just sue ACME for crap products, I have no doubt his 270 IQ can read the directions and they still always go wrong.
I am quite certain he uses the products in such a way as to void the warantee.
For instance, the refrigerator, ice chipper and skis each worked perfectly well - it was the combination of the items being used in a manner the designers had not foreseen that caused the disaster.
In the movie Looney Tunes - Back In Action, Wile E. worked for Acme. Maybe he had a clause in his contract that held Acme non-liable in the case of injury.
