CHARLOTTESVILLE, Va. — Nearly 90 percent of the country's neo-Nazis and white supremacists are thought to live in a secret underground base they refer to as "mom's basement," sources confirmed today.

The secret Nazi base is where white supremacists go for ideological indoctrination and to hoard supplies of Hot Pockets and non-kosher pickles, officials said.

There remains an air of mystery about the figure called "Mom" — believed to be the leader of the American neo-Nazi movement — and exactly what else she is hiding in her "basement."
