Don't ever, ever host a college party -- unless you want to spend days/weeks/months cleaning up the subsequent mess.

However, if you decide to throw caution to the wind and undertake this daunting task, make the party a good one. And everyone knows that the only good bash is one whose aftermath bears these eight signs:

1. Counter-to-Counter Empty Bottles (AKA The Recycling Plant)

2. ... And Counter-to-Floor Bottles Too

3. Plates Filled With Food You Cannot Easily Identify

Everyone gets the munchies when they drink, but don't try to be an Iron Chef and whip up some culinary masterpiece from scraps.

4. The Couch Dweller

Bonus Points: You have no idea who the guy on your couch is.

5. ... And His Cousin, The Toilet Tenant

It's not a good party if someone doesn't pass out next to your toilet. This is a fact.

6. The Party Love Stains

Note: People with carpets should never host parties.

7. Unexplained Property Damage

Wait... How'd these scorch marks get here?!

8. The Mysterious Inflatable Pool of Beer

Unless you have children, you shouldn't own a kiddie pool. Yet, you've found one on your lawn, and it's filled with beer.
