Meh-Only Holiday -- Irony Day

ThunderChicken thought this was worth mentioning said

On this day in history:

On August 28, 1957, Senator Strom Thurmond began his filibuster of the bill that eventually became the Civil Rights Act of 1957.

On August 28, 1963, Dr. Martin Luther King Jr. made his stirring and famous “I Have a Dream” speech.

What ironies can you name (not necessarily date coincidences)?
