—Various bystanders throughout the Casper cartoons
"(Casper) has to be the cheapest character design ever. It's just a construction model for a stock 40s baby character. It's such a funny concept to have a character without a design or any details at all. Even ears are too expensive to draw! There are a million characters based on this construction, but this is the only one that is nothing but construction."
—John Kricfalusi on Casper's Bedsheet Ghost design, "Naked Dead Baby With Dangling Parts Cut Off Construction"
