WTF Fun Fact – Billionaire Plans To Bury Bentley

Thanks for commenting this, I thought he was making an excuse to calm the media.
This is so awkwardly phrased that it leaves a lot of context behind.
The reason he specifically pranked about wanting to bury an expensive car, was to expose the irony behind being outraged by burying a valuable vehicle, while a much more valuable thing is being buried all the time (organs, which can actually save a life).
