After signing up for that free nugget, I have no way of getting back to the main Page.. this is a little annoying. Also, that gif.. i don't know it's a little weird. And, are you sure you are allowed to use that on a commercial site?

Regarding gifs, on your 404 page there is another gif, with copyrighted material, and even a Netflix logo visible, I doubt you have the permission to use this in a commercial way.
