Just because it's the holidays doesn't mean there aren't spooky ghosts around! Just ask Mike Dev. His baby and fiancé were chilling in the living room when their Christmas tree fell down for no reason! Obviously, the only explanation is ghosts.
The same thing happened to That Chipper Bunch. The family was sitting in the living room, minding their own business, when the Ghost of Christmas No Chill brought the tree down on one of the kids! Then it fell on another. That's one mean Christmas spirit!
