ELUSIVE BRIDEZILLA CAPTURED ON FILM!
For one thing, that is a DOG standing on their table. The head height behind his shoulder is proportional to where the dogs head would be if it was standing there behind him, on the table. Also look at the crappy peeling wall behind the table. Looks like they were married in some gym at a high school. Most likely they had the gym doors wide open, and all kinds of stuff wandered in. Or some maniac dog lover had some dog they could not part with there, and it was not leashed, like it should have been. Which is why some dumb mutts dumb mutt didn't belong at their marriage.
Now, if there was no table directly behind him that FIDO could jump up on, I would have to be more skeptical about how it got there. But a dog standing on a table? Give it a rest already. He needs to go back and do more drugs if he believes this one. But then they can't go all over the place talking about their relatives dumb mutt who jumped on the table and ate on the cake, because who cares? And in the video shes got a DOG draped on her shoulder like its a mink stole or something. I'm sure the FIDO in the wedding picture was just looking for some shoulder action.
Moral of this story: DON'T EAT THE CAKE! The dog already licked it and wiped his butt on it!
