For those of you that have seen the viral video, there is an hour special on Animal Planet right now with all the back story of Christian. It's really good, I suggest watching it.
For those of you who don't know who Christian is, he was a lion that 2 gentleman purchased in Harrod's dept store in London in the 60s as a cub. As he got older they had to make other living arrangements for him, and the viral video was when they went back to visit him. Have tissues ready. Happy tears!
