Tall tale collapses

Comedian Steven Rannazzisi (FX's "The League") has admitted in a series of contrite tweets that his often repeated story of a harrowing escape from the World Trade Center on Sept. 11 was fabricated. "I was in Manhattan but working in a building in midtown and I was not at the Trade Center on that day," he said. "This was inexcusable. I am truly, truly sorry.
