This dumbass is incredibly fortunate that he's not a dead Doofus candidate. See for yourself.
That was filmed in the Serengeti National Park in Tanzania. You can read more about it here.
I've lost count of the number of stories I've heard (and incidents I've personally witnessed) of dumb tourist behavior around dangerous African animals. There are just as many involving dangerous American animals, of course - and not involving animals at all. There are so many, in fact, that the word "tourons" (an amalgamation of "tourists" and "morons") has been coined to describe such behavior. Do a search on "tourons" and you'll be amazed at some of what you read. There's even an entire Reddit subforum dedicated to them.
A tip o' the hat to reader Gerald F. for sending me the link to that story.
