Seeking Forgiveness from your Grill, or your Audience?

When the white guy's lounge chair collapses, sending his food sprawling, the immediate reaction of the black guy is to point and laugh.  Because he's an asshole.

The immediate response of YouTube viewers who see this ad is to post how much they love it, because they are assholes who like things they know are supposed to be funny Because Reasons. 

I'm convinced that most viewers have the brains of young house cats who react instantly to shiny objects in the form of cliche'd crap on tv.  Cats react instinctively to laser pointers, dangling string, and mice.  YouTubers react instinctively to people tripping, falling, getting seriously hurt, or just plain being humiliated in a moment of vulnerability. 

So this ad- featuring absolutely nothing more than a guy's chair collapsing causing him to lose his food and then being mocked by another guy ten feet away who actually interrupted his conversation with another human being to do the mocking- is "funny" because.....again, I don't get it.

And I CERTAINLY don't get why this ad is supposed to make me want to buy a grill.  Because it's "forgiving?"  A lounge chair might collapse and force me to get up, clean myself off, and go get some more food.  What can a grill do?  Give me third-degree burns.  How is that "forgiving?"  What does all this even mean?
