Extra Credit Questions

[RJNorton]

Yet another excellent guess, Bill, but incorrect.

Hint #2.5: The alleged incident involving Lincoln was used in 1973 as a stratagem to try to get President Richard Nixon to do something; as expected, Nixon refused.

Hint #2.75: Carl Sandburg included the 1863 incident involving Lincoln in The War Years. But I think most experts nowadays think it never happened.
