Colon Blow

A man eating breakfast is interrupted by an unseen announcer promoting a supposedly superior high-fiber cereal. Asked to compare its fiber content with his usual oat bran, he keeps offering modest guesses. The commercial answers by lifting him and his breakfast table onto a towering pyramid representing more than thirty thousand bowls of ordinary cereal. Just as he accepts the comparison, an even stronger version of the product sends the mountain higher still, now representing millions of bowls. His mounting alarm gives way to a cheerful product display and a discreet warning about the cereal's effects.
