Olbermann On Lieberman: Part Of Olbermann's Ouster?

One is forced to wonder what did Olbermann know and when did he know it?

Olbermann either:
A. Knew he was soon to be out and took the opportunity to slam the slimy Lieberman
or
B. Had no idea his ouster was soon, attacked Lieberman correctly, and then was ushered out the door because of it.
