Two And A Half Men picked a bad episode to have a Judith and Alan reunion. I expect it to be short-lived, but they dropped that bomb on an episode that was not the funniest of all time.
Charlie had some good lines including Poland taking a wait and see approach to Germany's invasion, his continued insults of Jake and his sarcastic responses to Herb. Herb was funny as well in his limited capacity.
I did like the final scene with Alan suspecting that Herb and Charlie may have slept together when he saw him leave with a Charlie style shirt on. Just not that great an episode overall though.
