A Man Needing Help...

There was a blonde woman whose name was Beth. Beth had a boyfriend named Robert. One morning, Beth called Robert:
Robert: Hello?
Beth: Hi Robert! I am having a problem with this puzzle, I can't put ANY pieces together!
Robert: I will be right over.
So...Robert comes over to find Beth sitting at the kitchen table and Robert sighs and says:
Robert: For goodness sake Beth! Put the Corn Flakes back in the box!!
