Some people like to hear themselves speak.

Traditionally, these are radio people. So much so that the "puking DJ" has become a staple of every-day conversation.

But the question entered my mind: Does George Clooney like to hear himself talk? He does essentially the same thing as the DJ, just in a more solemn and believable way. They both (theoretically, at least) earn fans when they nail their parts.

Why would Clooney (or any other actor of any serious cachet) not like to hear himself speak?
