A funny moment was when I was being chased by a Dwarf Warrior once a long time ago and he was making damage progress on me.  However about a minute after he attacked me, he suddenly started walking instead of running.  I ran far far away and then healed.  I waited a bit and noticed he was still walking.  He mounted up and continued to walk still.  I realized that he probably hit the / key and didn't know how to make himself run again.  So to tease that Alliance bastard, I ran up to him, knocked his health down to about 10% then stopped and kept doing that for about half an hour.  He logged out a couple of times hoping it would 'fix' his walking problem. 

Ah, fun times. 

I have to say though, I am surprised that some people don't know about the walk/run feature.

I have a lvl 65 Warlock and fighting Boulderfist Og's when I started getting harassed by an Undead Mage name of Marik. My lock is name of Undertakeher, Releam of Shu'halo. I had just lost my Imp when he challenged me to a duel. I decided to see how I would stack up so I excepted the duel. I rolled of Death Coil, Fear, UA, Corruption, CoA, Immolate, Incinerate and had me a lvl 70 dead Undead Mage. Hurt his feelers so bad he wont duel for anything now. Can't make enough fun of him or be rude enough to make him duel anymore. I even flagged and he wouldn't even go for a kill.
