Just how hard is it to kill a Troll?

It's easy. You just butt him off the bridge with your head.

hahaha I always loved tht story, so when I was introduced to Tolkien it was rather hard for me to get that out of my head. I kept thinking (and still do sometimes!) That they were rather small creatures, not the big things like the cave troll in the movie.
