You have to be living on Pluto if you haven't been tagged by innumerable people in posts where they tell their all time top 10 books, and ask you to state the same. Some intellectuals with overgrown right brains have named it the #BookBucketChallenge. Some scientists speculate that these might be super evolved humans who keep their books in buckets and can read the books just by overturning the book bucket onto their heads.
Although Zahi Hawass says, "these are the people who were bitten by mummies(slang zombies) who escaped King Tut's mansion. Then the world had only 9 books which were spread over inaccessible locations namely Marina Trench, Mt. Everest, North Pole, Antarctica, Mt. Fujiyama volcano, a blue whale's jejunum, under Hagrid's beard, fixed price stall behind 60% flat off at Zara, the statistics cupboard just behind playboy section in National Congress Library and under stacks of Indian money in Swiss banks. Whoever tried to overthrow the pharaoh was given the 10 books challenge. Since no one could ever find the 10th book, King Tut enjoyed his throne eating grapes off then Miss Universe Nirupa Roy. Hence, the infected 21st century people still believe it is Tutean task to name 10 books". "The challenge can now be completed by just Harry Potter and Toilet(sic)", he laughs.
