Richard Nixon had a very strange idea that he did not want any pigeon poo to appear in the path for his inauguration. Of course, as the President he had the power to go ahead and do what he wanted about it, but it could be argued that he did take things a step too far.
His idea was that they would spend $13,000 on a chemical that would be sprayed, along the route that would stop the pigeons from being there and pooping. However, the chemical that they actually used was toxic to the pigeons and instead of there being pigeon poo the inauguration route was littered of dead pigeons which is infinitely worse.
Perhaps he should have taken this as a sign that his time as the President would not go well, so if there are ever any dead pigeons in the future, then perhaps that individual is not going to see the end of their term in office.
