However as much discussion we've had about the internet remembering everything, I can't find anything in Google to confirm "Microsoft Coffee" except for this site, discussion of it on Reddit 13 hours ago.
I hope that if you're being serious about 11 being the max, that it was a deliberate reference.
AFAIK there is no way to view all of those millions of results that they claim to have.
Honestly this prank makes more sense to me as a forgotten thing than as a modern meta-prank. I would not be surprised if Bill or some other prime mover from that era hears about it and confirms at some point.
In the 1990s they released "drag 'n' drops" - a gummy candy in the shape of dragons. I can't find any mention of them.
Stuff like this seems whimsical, but it serves the very serious purpose of allowing Microsoft to claim exclusive use of their name in that class.
Google has lost a lot of old posts from those days, but I'd be surprised if it would have lost all of them.
Internet Explorer only launched in 1995, and the anti-Linux Halloween Documents were 1998.
Its choice not to display any information older than the attention span of a cracked out chipmunk is one of the main reasons I stopped using Google.
"stale as buns" is my phrase of choice.
(even i'm cringing at the metaphor, but if you think about it, it sums up what i'm trying to say. Pretty well)
Perhaps, however remember the Mandela Effect. I'd expect ong time KOMO viewers and staff to recognise the presenters, and I'm sure they were the right ones. I wouldn't trust their recollection of this story though, especially once they had seen the video - after all the camera never lies.
Remember news anchors read dozens of these stories a day, to recall one specific prank 25 years later isn't likely. Unlikely KOMO still have recordings of their output from back then.
KING ran retractions for days, and did their best to bury the footage.
I saw it when KING ran it, and had a good laugh. It was an obvious prank (the video looked like a bad cut & paste job, and the reporters were local comedians from "Almost Live"), but too bad a handful of humorless people ruined it.
I ran into Bill Nye some years later and asked him about it, and he replied they got into a lot of trouble for it.
Almost Live was always making fun of Boeing, Microsoft, cops, local sports fans, anyone who lived in Kent, gangs, local hair metal bands, etc. All in good fun.
(They even got the hair metal band members to come on the show and parody themselves.)
