13. Crayola Crayons
Estimated Profits: undisclosed
While the modern-day Crayola crayon was first developed in 1903 by a pair of cousins who were in the industrial coloring business, these days they're produced under the watchful eye of parent company Hallmark, who acquired the company in 1984. Hard numbers are hard to come by, but if Crayola's producing the 3 billion crayons, 600 million colored pencils, 465 million markers, 110 million sticks of chalk, 9 million Silly Putty eggs, and 1.5 million jars of paint they claim to annually, it's safe to assume they're lighting cigars with multiple hundred dollar bills.
