You know it's time to do laundry when....

 ...you go commando not because you enjoy it (you don't), but because the underwear drawer is empty!

 Not that that happened this morning.... 

...when the sock-thief dog has dragged another sock into the yard and you have no more matching pairs.

 ...DH buys another pack of socks

So buying new clothes is not the solution? crap. guess....I should finish my laundry then, since I'm out of pants!

...when you call in "sick" to work because you don't have anything to wear. 

When you wear pre-distressed lightwash jeans, a Cubs jersey, and flip-flops to work (and it helps that the boss and half the department is on vacation, plus a day with no meetings or work appointments).

 ...when you catch your dog sneaking into the bedroom because he wants to take a nap on the giant pile of dirty clothes waiting to be washed. (Way better than his actual bed, because it smells like dirty people!)

 ...and you're out another pair or two of undies, because he found them and is snacking on them. While resting on top of the rest of the laundry.

Good, it's not just me then!

*Hangs head in shame*  That is how my room looks!!!  It seems like the more I wash, the more clothes that mysteriously appear in the hamper!

You debate which pants your wore for the least amount of time, and figure the ones worn the least are the ones you should wear again.

You know you should have done it earlier when you are getting ready to go, and are debating which pants are the closest to being totally dry, or which would be least uncomfortable.

...you actually respond to this thread purely as a means of yet again putting the hated, endless chore, off!!

 Courtney, give Rascal all of your undies, & go commando.  It's much easier!

Lisa, it's not just you.  It's happened to me.......more than once.

Why am I in this thread? Ohhh, I buy the laundry soap and the hubby does the laundry.

 I always have clothes, dang it.

 when you walk in the bathroom and find clothes that were stuffed in a hamper all over the bathroom floor because the DH couldnt find any clean jeans so he had to dig to the bottom to find the jeans he wore only once.

Basically anytime you have to smell something to see if it is clean enough...
