Donkeywalloper - what a fantastic idea - the only way he can possibly dodge that one is if he has absolutely no 'feelings' at all. Anyway it would still make him look bl**dy stupid - I really like that one!!!!!
Tell him your room has been broken into and your money and wallet containing everything has been stolen and he will have to pay for everything untill you get back home.
Then when walking through your front door fake a trip pretending to hit your head and claim you can't remember anything of the holiday. Its a winner.
