If you need a good laugh, check out a blog I just found called Cake Wrecks. I'm actually snorting, looking at the pictures and reading the blogger's commentary.
There's the bride who commissioned a cake that looks almost exactly like her. There's the cake with a little naked frosting woman giving birth to a little frosting baby on it. There is also the big pile of dung on a cake, surrounded by flies.
And the kicker? These are all professional cakes!
Check it out.
