Just do what most students do and have a party most likely to get you expelled by the Dean once the Daily Mail has published details of your shameful behaviour.
Suggestions would include:-
The Maddie Party. You all go as potential villians in the Madelaine McCann 'mystery' – someone has to go as the mother though.
The Prince Phillip Party. You all go as minorities, nations, individuals PP has insulted in the last year. Could be a large do mind.
The Dead Pool Party. You all go as people you think will die in the coming months. Keep a record, and the first one whose celeb does actually croak gets killed.
