There's a conspiracy theory that Chuck E. Cheese reuses uneaten pizza . . . mostly based on the fact their pizzas always come out misshapen with slices all different sizes.And the conspiracy theory is getting a lot of attention now because of a new video about it by the YouTube star Shane Dawson.Chuck E. Cheese vehemently denies the rumor, by the way. I am still searching for the original video, it looks like Chuck made Shane take down the video.
