Once when the Bishop was visiting our Church, I was in the altar as an altar boy, and as he was getting ready to give the sermon, I asked him what the best sermon he ever gave, he told us the best sermon is the shortest one.
I have to say that in my experience, going back a fairly long time, most bishops do not adhere to said policy. 
If I remember correctly he also was long winded, but he also loved a good laugh.
