Bows and arrows - if you're that sort of person - are only allowed during a few days in October, but otherwise the methods to use include sweet talking and iambic pentameter.
Come here my friend with one big shiny horn

While my dubious poetry might not be the best way to win the heart of a unicorn, you may have better luck if you are granted a Unicorn Questing Licence. Available from the Lake Superior State University (Mythical Division) you can apply online for the right to quest for unicorns.
You can be granted your very own Unicorn Questing Licence
Before you mutter that unicorns aren't real, don't forget they were mentioned a number of times in the bible, and have been part of our lexicon for thousands of years.
There are certain rules for Questers such as the law against the use of artificial light (so don't bother using the flash-light app on your iPhone) and you must pin your licence above your heart with a sprig of rosemary.
There is even a recommended list of items required for your questing kit including a large envelope, pinking shears and small flask of cognac.
The Unicorn Hunters were established in 1971 by the late W.T Rabe, who was also responsible for the annual List of Words Banished from the Queen's English for Mis-Use, Over-Use and General Uselessness. In 2013, banished words and phrases include 'fiscal cliff', 'trending' and 'bucket list' where 2012's included 'baby bump' and 'man cave'. Click here for other lists of Banished Words.
You can always turn your unicorn into a pair of slippers
So grab the nearest virgin (as they are a great help when searching for unicorns) and download your Unicorn Questing Licence. Remember, only those pure of heart can catch a unicorn – if you are guilty of a mortal sin, they're quite likely to run you through.
