Here's the first one that I saw, but it was posted without context. One could say all kinds of things about the folks in this photo, but I think the guy on the left is saying it all. :)
Then we have the second photo that... well, to put it mildly, bride realises she doesn't have to outrun the dino, just the rest of the wedding party, especially the second girl from the left who hasn't realised that if you pull up the him of your bridal skirt, it would be easier to run. Of course, if the bride tosses the bouquet back and it is caught by the T. rex, then that might serve as a minscule distraction!
Still, what is it with photoshopping dinosaurs into wedding pictures the last couple of days? :)
