I no longer fear hell, because....

“I’ve been to kamp krusty.”

Most people know this qoute form the simpsons, but I keep thinking that this is actually based off a real qoute.

So I ask, is this based off a real qoute, and if so, what is the original?

It is reminiscent of the Marine’s epitaph, found on a Lunga Point grave on Guadalcanal:

“I no longer fear hell…” appears in a lot of places. I am not at all sure where it originated. (It might very well have begun with the Simpsons, as I have not found any really old citations.) It does not appear in Bartlett’s 16th edition and I do not have Bartlett’s 15th (the last before it was seriously “modernized”).

The 10th edition of Bartlett’s is available here, but I can’t find anything containing “I no longer fear hell…”.
