I wrote a lot of stuff that they never used on Scooby Doo. I had the gang joining forces with the Buddha on one episode and when ever they would come across a clue they’d talk it out and ask the Buddha what he thought and he’d always shrug and say, “Yeah, I’ve got nothing.” and the audience would laugh.
I also had Scooby and Shaggy kinda making fun of him by acting all pious and meditating. Shaggy would look at Scooby and say, “Hey Scoob! Whats the sound of one hand clapping? and then he’d swallow a whole banana cream pie and say “Yum!” and Scooby would snicker.
The end involved the Buddha being chased by a mechanical gorilla in a pink tutu.
