Seriously....tongue-in-cheek!

The timeline, however, is correct. Al Gore was @ Harvard in 1967 and Jim Delligatti did indeed introduce the Big Mac at his Uniontown, PA McDonald's franchise in the same year. The rest of the story is all speculation on my part.

While I'm on the subject, does anyone remember the advertising campaign which celebrated the 20 year anniverasry of the Big Mac? I'll give you a hint. It involved a singing moon and a piano. I found the original on Google/YouTube. Enjoy!
