I mean, for cryin' out loud, suspicion has been cast on Undie in a BIG way for a week and a half now (at least).
It just doesn't make sense to me. If I were Undie, I would have nipped all of the hoopla in the bud by letting Skinner verify it. Why has he let this suspicion grow?
Two reasons.
Number one, Andy has been felonious all his life, and is utterly incapable of doing anything straight, such as telling a straight story.
Number two, Andy does not want the Grand DUmmie "Skinner" to know the truth, and the Grand DUmmie "Skinner" does not want to know the truth.
