When I was growing up, my dad had visited Seattle and came back from the trip with a box of Microsoft Coffee. He claimed to have gotten it from a store called Egg-Head’s Software or Egghead Computing or something like that. (EDIT: Upon reading the full article it seems to have been Egghead Software.)
I took it to my computer club and was laughed out of the room for it being fake. I believe he still has it somewhere, in storage...
Needless to say, I have some friends to email given that I’ve been the victim of “my uncle works at Nintendo” style teasing about this for years.
