The phenomenon, reported exclusively by frustrated dieters, of weighing more after a full evacuation.
Having sucessfully dispatched a massive, Niles was more annoyed than surprised to learn he'd gained another 2 pounds.

"Great" he muttered to the scale, "a negative weight shit". "Dieting's not hard enough, now I gotta contend with alternative physics".
Later on he resolved to remove nearly all anti-matter from his daily menu.
