As a LOOOOOONG time lurker first time poster I would like to say you 
are all nuts - and I love you for it.  I only wish I could think up 
a tenth of the the stuff that gets thought up here...

However, on to what drew me outa my lurking...

For best yes moment how could you have missed

Umbridge : "I was just wondering, professor, whether you had 
recieved my note telling you of the date and time of your inspec - "
McG : "Obviously I recieved it, or I would have asked you what you 
are doing in my classroom,"
Umbridge : "hem, hem"
McG : "I wonder, how you expect to gain an idea of my usual teaching 
methods if you continue to interrupt me?  You see, I do not 
generally PERMIT people to talk when I am talking." (emphisis mine)

God I loved that scene
