The Apollo of Delphi was the god of black jokes. Herodotus says that Croesus, legendarily wealthy king of Lydia, feared an attack from the envious Persians. He couldn’t decide whether to hold fast or launch a pre-emptive strike, so he sent emmissaries to consult the oracle at Delphi. She said that if he crossed the River halys and attacked with vigour he would destroy a great nation. He did, in 532 BC, and he did destroy a great nation, his own. His army was annihilated.
All that is generally remembered about Spencer Perceval is that he was the only British prime minister ever to be assassinated. By all accounts he was a thoroughly decent, honourable and competent man, but he was cut off in his prime and failed to make any lasting mark.
