Exploding Butter

Have a laugh at our expense. I was in the kitchen talking with my aunt while dinner was being made.  She put some butter in the microwave and set it to defrost to melt it. She turned it on and we were talking. All of a sudden.... BOOM... and splatters inside the microwave as we watched in horror.  The butter exploded in the microwave.  It was literally dripping from the ceiling of the microwave and off the door when we opened it. On the bright side, now everything smells deliciously of butter.
