Example Input: The four-leaf clover is a rare variation of the common three-leaf clover. According to traditional superstition, such clovers bring good luck, though it is not clear when or how that superstition got started. The earliest mention of ``Fower-leafed or purple grasse'' is from 1640 and simply says that it was kept in gardens because it was ``good for the purples in children or others''. A description from 1869 says that four-leaf clovers were ``gathered at night-time during the full moon by sorceresses, who mixed it with vervain and other ingredients, while young girls in search of a token of perfect happiness made quest of the plant by day''. The first reference to luck might be from an 11-year-old girl, who wrote in an 1877 letter to St. Nicholas Magazine, ``Did the fairies ever whisper in your ear, that a four-leaf clover brought good luck to the finder?''
Example Output: is there such a thing as a four leaf clover?
