Magna Carta Day, explained in the style of Jeff Spicoli:
In 1215, the king of England was a total wad, so a bunch of rich baron dudes got together and decided his divine right was bogus, so they drew up some cool rules they called the Great Charter until somebody said it sounded way more righteous in Latin. They took it to the king on June 15th and told him, “Sign it, or you’ll never party again,” which was a gnarly scene for a minute, but then he signed it.
The Pope was not cool with that and said, “Later, dudes!” and kicked all the baron guys out of the church. But none of it matters anyhow because Julius Caesar’s calendar was a mess so we use a different one now, which means the Carta got signed on June 8th but then, like, did it even happen?
