Hey, I actually get this obscure xkcd reference:

We did three Entertainment Packs for Windows soon after Windows 3.0 came out (tagline:
“Not the most fun you can have with Windows, the only fun”).  Each had about
eight games.  Some like Minesweeper and FreeCell got bundled with subsequent
versions of Windows, but I never would have guessed SkiFree would continue to have
a cult following nearly two decades later.  There are SkiFree updates, ports, exhaustive
overviews, numerous
videos, cheat codes, fan
mail and even fan fiction. 
The Wikipedia entry has even dug
into the philosophical
underpinnings of the game (though inexplicably provides no scatological discussions
of the sources of and scoring for yellow snow in the game).

The funniest part is (if I recall correctly), the origin of the Abominable Snowman
was the game had a stack overflow bug and instead of fixing the bug (hey, we were
on Internet time way way before it was popular, cranking these things out in a couple
months), the Snowman was introduced as a way to sidestep the bug by devouring the
player with a small loophole that if you outran him in a specific
way (appreciate the annotated video and opportunity to buy the soundtrack…), you’d
start again.

I
assume it is just a matter of time before the Snowman gets a movie deal.  Every
other comic character with any nostalgic appeal already seems to have one.
