This video will make you cringe, gasp and chuckle as you watch Santa jump, run and roll off rooftops. These amazing videos demonstrate something called parkour, which is defined by Wikipedia as a skill in which 'Practitioners aim to quickly and efficiently overcome obstacles in their environment, using only their bodies and their surroundings to propel themselves; furthermore, they try to maintain as much momentum as is possible in a safe manner.' You go, Santa! But do not try this at home. After all, you aren't Santa!
