The traditional 'Ask A Stupid Question Day' in America has now made its way into Britain''s schools, encouraging pupils to ask teachers the daftest things they can think of.
The practice, which dates back to the 1980s, took place on September 28, which was the last day of the school year.
And to mark the occasion, the Telegraph has revealed some of the silliest questions ever posed in Britain to date, as asked by users of the Any Questions Answered (AQA) text service.
Ten best questions asked by the kids were:
Q: What''s the opposite of a camel?
A: The opposite of a camel is a soap dish: it has dimples instead of humps and lives in a mostly moist area.
Q: How long would it take to roast a fully-grown Indian elephant?
A: An Indian elephant, average weight 5000kg, would take 2916 hours and 40 minutes to roast to perfection (based on 35 minutes a kilogram). You would need an extremely large serving dish.
Q: In Mars Bars, how much taller is Jeremy Clarkson than Tom Cruise?
A: A Mars bar is four inches long. Jeremy Clarkson measures 19.25 Mars Bars (six feet five), while Tom Cruise is 16.75 Mars bars high (five feet seven). That''s a 2.5 Mars bar difference.
Q: How long would it take a snail to slide around the world?
