Quote: Skorski's other brush with fame came via a March 25, 2000, Washington Post article about the controversy surrounding an exhibit at New York's Whitney Museum: On Thursday afternoon, as hundreds of people waited in line to be among the first to view the Biennial, a lone protester stood in front of the museum, holding up a homemade poster that depicted Rosie O'Donnell, Hillary Clinton and Alec Baldwin wearing swastika armbands. Alan Skorski, 37, wore a yarmulke, argued with museum-goers and said he was objecting to the exhibit because "enough is enough."
