Party Crashing Etiquette for the Host

You've invited 17 people, and now you're stuck with the bill. Don't sweat it, just wing it.

Here are some tips to help you survive the party like a pro:

Bring a few spare snacks to "forget" you're hosting, just in case.
Have a secret escape route planned, like a fire exit or a well-hidden wine cellar.
Be prepared to explain why there's no more beer.
