Although the events in this video took place in the 70s, the story of a captive lion released back into the wild only to recognise its prior rescuers is clearly still tugging at the heartstrings. Since this video was added in June, over 7 million people have viewed this emotional reunion, which is certainly worth a few minutes of your day.
Just turn the sound down if you're in a public place (unless you're really fond of Whitney Houston and all the people around you are too).
It certainly stretches the definition of what we consider a pet... Now imagine getting that every day from a pet dog, grateful that you'd given him a forever home. Alright, perhaps not a fair comparison but certainly a good bit less unpredictable!
