There are a number baffling Guinness world records in the martial arts category.

Most sheets of glass broken with a single elbow strike:

Human Bed of Nail Sandwich:
6, by Oscar Braganza, Daraius Cooper, Shahaan Davierwalla, Hanoz Kasad, Vispy Kharadi, Priyank Rana, and led by Vispy Kasad. Combined weight of the people forming the layers was 462 kg (1,000 lbs +).

There is also a category for Three Taekwondo Black Belts attempt the highest assisted kick world record, which is only a little weird. And there are others make more sense, like the highest Taekwondo kick ever, as Taekwondo is known as a kicking art.

The attempt was made by Pascal Gentil, the greatest Taekwondo practitioner in French history, and a man who does things his way.

The three-time winner of the European Championships, four-time World Cup Champion, and Olympic bronze medalist at the 2000 Summer Olympics in Sydney and at the 2004 Summer Olympics in Athens, appeared on French television and attempted to kick over 2.60 meters (8′ 6″).

Gentil himself is 1.98 meters (6′ 6″) tall, giving him a leg up on the competition.

Guinness World Records, known from its inception in 1955 until 1998 as The Guinness Book of Records and in previous U.S. editions as The Guinness Book of World Records, is a reference book published annually, listing world records and national records, both of human achievements and the extremes of the natural world. The book itself holds a world record, as the best-selling copyrighted book of all time. As of the 2016 edition, it is now in its 62nd year of publication. The international franchise has extended beyond print to include television series and museums. [source : wiki]
