Targeting that religion online in any comedic / mocking way is a big no-no. It only ends up causing offense or a stuffstorm. You'd probably get acid in your face if you lived in an Islamic country and showed that to people, you always here of bizarre horror stories like that.
I didn't find it funny either. I'm not sure why... the joke just felt very weak and flat. Perhaps insult to injury it goes out on cliched schtick of zooming into someone random.
I dunno, this just feels to me like a lack of effort went into thinking of a concept. As if you just took the chance to make a vid with some friends.
