"Death" of King George III

King George III was reported to have died at Windsor Castle in the year 1820. We now know that this was a false demise, as King George has resurfaced in the town of Pleasanton, California under the guise of Drew Melby, a chemistry teacher. However, the exact details of the events between his death as a king and current residence at Amador Valley High School are cause for speculation amongst several melbytologists, all of whom are (self-identified) complete trash.
