Yeah, those lesbos have their clandestine meetings in Al Capone's secret vaults. And for younger RJ members who may not remember that notorious low-point in US journalism, courtesy of the same Geraldo, here's the URL:
[Rivera] hosted the special The Mystery of Al Capone's Vaults which was broadcast live on April 21, 1986. The two hour special (including commercials) was greatly hyped as potentially revealing great riches or bodies on live television. This included the presence of a medical examiner should bodies be found and agents from the Internal Revenue Service to collect any of Capone's money that might be discovered. When the vault was finally opened the only things found inside were dirt and several empty bottles including one Rivera claimed was for moonshine bathtub gin.
The term "Al Capone's vault" has become slang for a heavily hyped event with disappointing results.
