It's all Cooper's fault.
Last night we had a lot of rain, which he hates. So he was up pacing and growling, jumping on and off our bed, and randomly barking (he hasn't figured out yet that barking at rain won't make it leave).
At some point Mrs. Grumpy decided to take him to the other end of the house to try and calm him down, and fell asleep on the couch.
As the night progressed the storm scared Craig, who came to our room. When he discovered my wife was missing, he climbed into the bed and fell asleep.
Then Marie woke up. When she realized her partner-in-crime was missing, she came to our room. She found him, and got into bed, too.
Frank got up to pee, and noticed the twins were gone. So he came to our room, discovered the situation, and jumped into the bed.
After the storm ended Cooper and Snowball came down to the bedroom, and jumped up with the rest of us.
I woke up early this morning with my left arm and leg, and most of my body, hanging off the bed because I'd been pushed off. And I was freezing cold because the kids had taken all the covers.
Mrs. Grumpy got a good night's sleep on the couch.
Stupid dog.
