Conan had one good week of ratings and that was the first week after that it got so bad that Letterman's repeats were beating new O'Brien episodes,

I stated the facts. Do some research before calling someone and idiot. BTW Leno wasn't losing to Letterman by that much.Before Conan took over, Leno's ratings were double that of Letterman.

Really, NBC's prime time lineup was dreadful for Leno and he was Number 1

He didn't take it over from Conan. Conan bombed in the ratings. NBC brought him back and was number 1 again.
