If you found David Cameron in your bedroom?

someone said his face looks like half a butt cheek wif two eyes attached...hit him wif me handbag...

I'd ask him who David Cameron is, then react accordingly.

EDIT: Well, now that I know who David Cameron is, I can properly answer the question. I would sit him down for a spot of tea and some crumpets. (stereotypes ftw!)

I'd tell him to get the hell out of my bedroom; given that he's PM, I would refrain from assaulting him, as I really don't want to create an international incident unless I have to - but if the bugger didn't leave post-haste, then all bets are off!

I'd say Hi, and then say who are you? and he'd be like: Im the new british prime minister and i'd be like oh thats tight sir" And he'd be like oh yea and then we'd be best friends and live happily ever after, best friends of all time

call the British police to put him in Scotland Yard

I would be seriously creeped out, considering I don't even know who that is, and would run away and call the police.

i'd do him he's hot
