Kevin Richardson works with lions and other big cats at a sanctuary in South Africa, and in addition to protecting and feeding the kings of the jungle, he also takes some time out to play soccer with them.
This video is a solid 2 minutes and 30 seconds of bad ideas, starting with a sharply-dressed Richardson jumping on a lion's back and wrestling the cat on the ground and progressing to him teasing a pack of lions by playing keep away with a soccer ball.
Richardson's Wikipedia page states he has only suffered some minor injuries at the hands (paws?) of the lions. If this is how he interacts with them, he is either great at his job, or the luckiest man in the world. [SportsGrid]
