It's a beautifully crafted story on the Royal Albert Hall's website about their archivist uncovering an old letter in their archives that protested to the Beatles the line in A Day in the Life about how many holes it takes to fill Albert Hall.
The thing is, when I read the story, it was several days after April Fools Day, so it didn't immediately register to me as being an April Fools joke. It did register to me that something was off with this, since it was such a ludicrous protest. But without the calendar staring me in the face, I will admit to being more credulous than I think I may have been otherwise. That's how well it's done.
P.S. One more reason why the otherwise wonderful John Oliver was so wrong about his rant against April Fools Day pranks.
