OMG Ink,
I read this some 10 years ago in the travel section of a local NY paper and its attributable to a travel agent in Bountiful, Utah. Still think of it from time to time, I think much of it is still relevant.
I even plagiarized the idea and penned a similar theme, "What If the Health Insurance Industry sold Pizza?" (I'm a healthcare provider) for some office yuks. Same concept.
What a nerd I am...
