It really is a word.  I heard it a while ago and decided I liked it.  So I looked it up.  Once I saw the meaning, I realized it was used very accurately.  Those House managers have absolutely benumbed me with all their repetition.  They seem to think that if they repeat something enough times, it will make it so.  All they have really done is to benumb us all.  Well, at least they did accomplish one thing, though I’m not sure it can be call an accomplishment.
