John Ehrlichman was sentenced on this day in 1974 for his role in the Watergate break-ins. To celebrate, hire a bunch of Cuban dissidents to break into your ex-wife's psychiatrist's office and rifle through her files. And if you try to link me to it, I'll deny it.

On this day in 1790, the first US patent was issued to Samuel Hopkins for an improved method of making potash. Celebrate by patenting something silly.
