What is the worst wedding cake disaster you have ever seen?

The worst wedding cake disaster I've ever experienced was driving a fondant cake to a reception already stacked together. I should have separated them and on the way and then put it together on the way there, because what happened was on the way there was that the cake totally fell apart. The top layer was smashed. When I got there, I had to reassemble the wedding cake practically from scratch. But with my experience the cake turned out rather well. I had extra fondant with me, so it was covered up very nicely and you couldn't tell that the cake had an accident on the way to the wedding.
