Baaa No wishing them 'good' luck! They kicked our asses last year.
Here is the 'luck' to wish them..
May your player bus get lost on the way to the stadium, and your players end up in paraguay.
or
May your cheerleaders all find out they are with child, and the Daddy be someone on the offense! None of them being able to exactly pick out the one guy.
or
May your tour bus be overrun with the fleas from a thousand hyenas.
Hmmm
May your QB slip and fall while 'putting his boots on' and pick up a concussion...
hey I'm on a roll..
Actually, I guess none of those really fit, so I simply have to wish you all good luck, and a great game!
