I dare say all performers have some ego, otherwise they wouldn't get up on a stage at all.
On the other hand there are snipers who hide behind *Guest* and lack the guts to use a name. That's one thing I appreciated about Clinton, at least he wasn't a coward.

If you have a problem with someone's ego, remember this story about one of my favorite characters: Someone told Winston Churchill that Anthony Eden was a modest man. W.C. replied "He has much to be modest about."
So, which of these men is most respected?
