You're getting company in 30 minutes. Your house is a mess.
WHAT WILL YOU DO?

SECRET TIP 1: DOOR LOCKS
If a room clearly can't be whipped into shape in 30 days - much less 30 minutes - employ the Locked Door Method of cleaning.Tell anyone who tries to go in the room that the door is intentionally locked. CAUTION: It is not advisable to use this tip for the bathroom.
Time: 2 seconds

SECRET TIP 2: DUCT TAPE
No home should be without an ample supply. Not only is it handy for plumbing repairs, but it's a great way to hem drapes, tablecloths, clothes, just about anything. No mess, no fuss.
Time: 2-3 minutes

SECRET TIP 3: OVENS
If you think ovens are just for baking, think again. Ovens represent at least 9 cubic feet of hidden storage space, which means they're a great place to shove dirty dishes, dirty clothes, or just about anything you want to get out of sight when company's coming.
Time: 2 minutes

SECRET TIP 4: CLOTHES DRYERS
Like Secret Tip 3, except bigger. CAUTION: Avoid hiding flammable objects here.

SECRET TIP 5: WASHING MACHINES & FREEZERS
Like Secret Tip 4, except even bigger.

SECRET TIP 6: DUST RUFFLES
No bed should be without one. Devotees of Martha Stewart believe dust ruffles exist to keep dust out from under a bed or to help coordinate the colorful look of a bedroom.The rest of us know a dust ruffle's highest and best use is to hide whatever you've managed to shove under the bed. (Refer to Secret Tips 3, 4, 5.)

SECRET TIP 7: DUSTING
The 30-Minutes-To-A-Clean-House method says: Never dust under what you can dust around.

Don't use them. Use plastic or paper and you won't have to.

SECRET TIP 9: VACUUMING

The key here is low, low, and lower. It's not only romantic, but bad lighting can hide a multitude of dirt.

SECRET TIP 11: BED MAKING
Get an old-fashioned waterbed. No one can tell if those things are made up or not, saving you hundreds of seconds over the course of a lifetime.
