First, you should know that there is nothing about this video that I don't completely adore. It might be one of the cutest things I've ever seen, and as you know, I have a Golden Retriever, so I see copious amounts of cute.
That said: Who''s the half naked dude? They cut away to him briefly, and it appears that he's watching the events unfold, but why is he not wearing a shirt?
When the lion first lunges at the big-haired-tight-pants-wearing fellow, didn't you think he was gonna maul him? I did.
Truthfully, I think it's a lab in a lion suit.
