Now let's be clear... I don't condone going out of limits but it happens so if it is going to happen at least make it as safe as possible. Do a loadsheet with assuemed weights of the examiner to ensure in trim etc and satisfy yourself that the aircraft is going to get airbourne safely and not out of balance.
I was once told by the chief pilot 'Weight won't kill you but the trim certainly will'.
