I just remember this short story:

When I was about 7 or 8 (around 1994), my dad had a computer at his office with MSDOS.

There I'd type "carmen.exe" and it would start "Where in the world is Carmen Sandiego?" or "pool.exe" would run a 2D Pool game I don't remember the exact name.

And yet, there was a "dolphin.exe" that I always thought it was a game but I never got it running. Obviously I don't remember what was the exact issue but to this day, 20+ years later it still bugs me to know what was this "dolphin.exe" program.
