help! One of my best friends is coming to stay with us, to watch a gig tomorrow. He's coming today until Wednesday. Now, he's a lovely lovely man, but has very little common sense.

He'd asked us if one of his friends could also stay at ours tomorrow night. This guy is a complete prick, but out of the kindness of our hearts, me and my housemate agreed that he could stay, so long as he behaved and didn't wreck our house or anything (which he is likely to do, from past evidence).

We've just had a message from my friend, saying 'we'll' be there in a couple of hours, so clearly we've got this other guy for the next four days. What can we do?
