A Brief Dilemma

Hi.  This evening, I am faced with a dilemma.  I thought I would be coming home after work today, at which point I had planned to do some much needed laundry.  But then...I got invited to have some beers with some new/old friends, one of whom was just in town for the night.  Then I started feeling guilty about my regular Thursday night friends, so I came back up to the northside to drink some beer with them, too. 

So I managed to drink 3 pints of lager, and finish 0 loads of laundry.  This is a problem.  More specifically: I am out of underwear.  What should I do?

1. Hand wash some underwear in the sink tonight and hope like fuck they're dry by morning
2. Wear dirty underwear
3. Wear swimsuit bottoms as underwear
4. Wear tennis bloomers as underwear

I know what you're thinking, and no, "no underwear" is not an option.  I'm not a fucking hippie.
