| Dr. Livelybrooks and his super-competent assistant, Bridget, formerly of Janice Gould's Eastside Elementary physics class, pose in front of their amazing discovery of tree-dwelling ghosts who routinely defy the laws of physics. Specifically they don't appear to accelerate towards the Earth in response to the force of gravity. They postulate that the ghosts have a very small rest mass, somewhat like neutrinos and, thus, aren't subject to load restrictions while travelling interstate highways. |
