Most people don’t buy so much as bubble gum without asking, “How much does it cost?” So for your amusement, I have assembled a list of costs arranged in an order that you may find entertaining. Hopefully, you’ll find the apples-to-oranges juxtapositions equally interesting. A tip of the hat for the idea goes to former colleague and mentor the late Ronald Khol.

Readers are invited to make what they will of the figures assembled here. These bits and pieces have been collected in a file for over a year and I have not kept track of their original source, although YouTube provided useful historical perspectives. What would you add?
