Do you want to be a BMOD? Do you? This advertisement, from the April 26, 1958 Los Angeles Times, helpfully describes the steps required to be that Big Man on Dates. Oddly enough, it revolves around Disneyland! Even more oddly, it uses DateNite rather than Date Nite. Perhaps created by a rogue marketing Cast Member?
At any rate, I'm happy to throw in "a buck for hamburgers and cokes" to be home free!
