You know what I would find funny (well, sort of)? If Zigs cashes in - fails - and then Cena has nothing to fight for in the match with Ziggler. AJ thinks he's fighting for her dubious honor, Cena goes out and lays down for Zigs because it turns out all he wanted was the briefcase.
Cena heel turn!
I think that's the best solution I have seen for TLC... well done Rob... I know it was sarcastic but I think it would be hilariously funny.
