Eccentric meaning the example that would be considered the most foolish or far out. I didn’t know a better synonym if the word eccentric doesn’t work. Most skeptics would understand the use of the word eccentric, but to give an example, the other day I met a little kid who couldn’t understand why the moon is invisible during its full moon stages and why it looks like a cloud, and the little kid said she thought the moon was just a cloud which has turned into rain during the new moon, only to evaporate again. But of course, this is a little kid, so in this case it’s not unnatural.
