SkiFree

SkiFree was one of the most simple and amazing games for early Windows Operating Systems in the Windows Entertainment Pack. There are a few different types of games in which you move the skier down the course gaining points. Besides trees, the main obstacle is the Yeti that periodically appears in the game and will destroy the skier.
The comic gets philosophical about death when the female character thinks that the Yeti symbolizes death because you can keep dodging the Yet, but it will get you in the end. However, the existence of the 'F' key to speed up those the girl's whole world into uproar. If there is an 'F' key in SkiFree, there must be something equal in real life, hence the 'F' pendant from the image text. I had no idea about the 'F' key to go faster.
You can download SkiFree from this site http://ski.ihoc.net/ - However, it looks like the xkcd effect has taken down the site. We will keep trying and update when it is back up.
UPDATE: Here's another site to download the game from and relive all your memories of SkiFree.

According to the wiki though, if you escape the yeti (which is actually meant as a time limit), you will enter a special level with 5 yetis.

I loved ski free! I used to play that on the Commodore in my 6th grade classroom.

“If there is an ‘F’ key in SkiFree, there must be something equal in real life, hence the ‘F’ pendant from the image text.”
I think you got this wrong. I think this is a sarcastic reference to how people wear crosses. Like, the cross is the key to eternal life, just as the F key is.
