Short version of longer quotes

Where can i find the full version of the shorter quotes?

Such as:

Great minds think alike

is actually a shorter version of

Great minds think like, small minds rarely differ.

Probably this is just a pop version -

Curiosity killed the cat but satisfaction brought it back

I have been looking for them since a while now, ever since I heard about Scooby Doo's darker interpretation.

EDIT - Are there any resources or website where i can find more of these?

"Great minds think alike" as the first recognizable version of the phrase comes from Carl Theodor von Unlanski's The woful history of the unfortunate Eudoxia, 1816

This was plucked from a very useful source that should answer this and your other curiosities. https://www.phrases.org.uk/meanings/great-minds-think-alike.html
