Nice bait and switch
I thought Karo was gonna light a fire under his ass, which would have been the obvious thing to do... instead, Abo attempts something clever. But the spontaneity was killed by the little facebook bit, even if that was an important gag to you.
At least justice was served in the end. Even though I like the Abo character, I feel very much pathos for Karo, being forced to live alone with his obnoxious, brain dead brother.
