On a Halloween night out 30 years ago Kim Goodman made an eye-popping realisation - she could pop out her eyes.
Kim was out with friends when she accidentally popped out one of her eyes when putting on her costume mask. In 1997 the Guinness World Records found her and since then she has had an unbeaten record.
Watch Kim demonstrate her unusual skill - but beware it is not for the faint hearted:
Kim originally had the record for being able to extend her eye balls beyond her eye sockets by 10mm. This was matched a few years by a new contender, but when Kim was re-measured she found she could now reach 12mm - breaking her own record and keeping the title.
