All good words.

I have always liked 'elbow' especially said in a deep voice and drawn out syllables! 

I was watching a film once, forget what, when someone asked what was their favourite word and I said 'elbow' out loud to a friend watching it with me, then we were surprised and laughed when the actor in the film also chose 'elbow'!
