I had the most fun pulling the leg of the employee. He told us that 'they' (the people who killed JFK and RFK?), couldn't kill Teddy, because that would be too suspicious, so they damaged his reputation ala Chappaquiddick. This was also right after JFK Jr.'s plane crashed, and of course, that was part of the conspiracy.
'They' apparently live forever, because he also said 'they' were involved with the Lincoln asassination. He never really explained who 'they' were, though.
