Love is in the Air Bloopers?

I was doing my Love is in the Air dailies and I noticed some WEIRD things!

Why am is this gun shooting backwards?  I thought it was a one off, but the spray is DEFINITELY going backwards, when I sprayed lots of people.

And I think that Vol'jin must have found last year's stash of cards that Garrosh didn't get through because he forgot to sign his name on this bunch!
