Just as a warning against odd urges:
Story 1
Once upon a time, I had a PC who was happily exploring the world. Not really realizing what I was doing, I found myself trapped in an ICly Bad(tm) predicament, effectively caught between a rock and a hard-place...or in this case, a very large cliff. Unfortuantely there didn't seem to be any way down...so I went through about every option I could think of.
Basically, after wishing up about it, talking to NPC's (humans, elves, and kanks), trying all the directional commands, and not getting a response, I was stumped. I wracked my brain trying to come up with a solution for my trapped character, running through all the commands I knew existed, and several ones I knew -didn't-. Needless to say, I was really very quickly becomming frustrated...and in frustration, I entered the word 'Jump', knowing it wouldn't work, either.
Alas, I was wrong. My character suddenly saw fit to throw himself off the cliff I was stranded on, killing himself upon the heartless rocks below.
Story 2
Once upon a time, there was a PC who was the proud father of a beautiful newborn baby. He loved his baby more than anything else in the world. One day, out of sheer curiosity, and to the utter amusement of the Staff, the player behind the PC decided to enter in the command 'eat baby', AND IT WORKED.
The moral of the story is:
It might not be a good idea to go randomly typing commands. You never know when one might work.
