You know that you have been doing the speechwriting thing for a while when you vaguely recall a good line you put in a speech, want to quote the person you wrote it for in the speech you are currently writing, and google the half-remembered phrase to find out who you wrote it for--
and get 190 hits quoting the person who gave the speech.
It's not like I want the credit. The paycheck is all I am after, believe me (well, that and the health insurance). It's just... weird.
