The game got 2 times better when this started happening for me. I got to kill a dragon and a thalmor death squad in a giant 3 way death dance.
Happened to me once. I was on the south road to Riften when I stumbled upon a couple of wolves. Buggers, I put them down in no time and then a message appears "You've been poisoned": behind me there was a giant frostbite spider!

To more swings and the insect goes down as well. I sheathe my sword but the combat music keeps going on... A troll is now charging at me.
At the time of this memorable encounter I was still at level 12 so I turned around and began kiting him around hoping to find some help on the road. Two dead farmers later I finally regain enough health to fight back. The troll finally goes down but the combat music won't stop. During my troll chase I ended up near an Orc stronghold besieged by giants!

One of the big guys is in dire need of a pair of glasses because he turns his back at the stronghold and he charges me instead!
