Okay, Pecker, I bow to your superior Yiddish-speaking skills. But the fact remains, I haven't been a total kvetch about those kinds of stories.
Whites came up with a lot of lovely stories about Indian origins which don't hold up to the evidence. Siberia was a good choice, until Charles Darwin came along and said that mammals with long arms and legs wouldn't survive long in that environment; DNA and geological studies around the Mackenzie essentially killed that theory. (In any theory involving Alaska, you get the same problem.) The lost tribes, advocated by Mormons and at least one bizarre Afrocentric group I met on Delphi, ignores 1) the absence of circumcision, and 2) the presence of all kinds of decidedly un-kosher behaviors. I've also heard claims of a Muslim presence; see the same as the lost tribes. Then there are the stories of Chinese travels to lands which most likely refer to Japan and not Mexico.
Then you get to the weird theories like Atlantis and Lemuria, or extraterrestrials.
