check out this clip of Christian the lion.
it's a true story and by just watching this short clip, i was touched to tears. it was a sweet reunion =) the story of this reunion has many versions to it on youtube but i personally like this version the best. the background song gives it more impact. just listen to the words of the song and watch the video and i'm quite sure if it doesn't make you cry, it'll at least make you wanna cry.
