how many boxer shorts? They call me Einstein Ali! I integrate like a butterfly, I derive like a bee!

How many pairs of boxer shorts should you own?

If you're like me, you put off doing laundry even if all you have left to wear is a greasy kilt and a Milli Vanilli t-shirt. But as soon as you run out of boxer shorts, it’s pretty much game over.

So you rationalize that buying more boxers means you save money by doing the wash less often. Yet eventually, the madness must end. The question is: How many boxers is too many?

Cost for One Pair of Boxers:
Estimate how much you spend per pair of boxer shorts (or whatever you prefer to wear). Use US dollars if in North America, euros if in Europe, or your local currency if you are elsewhere.
Number of Washers You Use:
How many wash loads does it take to wash all of your clothes?
Cost Per Wash Cycle:
You may want to add 10 cents or whatever for detergent and bleach. If you have a washer at your house, this cost will be low, maybe 30 cents for electricity and wear and tear on the machine for each wash load.
Number of Dryers You Use:
If you're one of those people who appropriate ten dryers to wash 10 pairs of jeans, this could be different from the number of washers. This could also be zero if you use a clothesline.
Cost Per Dry Cycle:
That is, how much do you pay to get the clothes completely dry (not just get the machine started)? This could be zero if you use a clothesline.
Opportunity Cost of Doing the Wash:
What is the maximum amount you would pay someone else to wash all your clothes for you (excluding the above costs for operating the machines), so you can sit home and screw around on the internet like you're doing now? Put that amount here. If you do your wash at home, this will probably be a low number.
Chance You Will See a Hottie While at the Laundromat (%):
What is the percent chance you will see a hottie while at the laundromat? If you're in college and don't go to MIT, this number could be very high. If you wash your clothes at home, this number will probably be zero (unless you live with sexy roommates). Now subtract from that number the percent chance you will see a hottie doing whatever you would do instead (ie, watch TV or play Nintendo, in which case, zero). Of course, if you work in at a modelling agency, this percentage could be pretty high. (Dream on.) NOTE: Enter a percent, such as 20, not a fraction, such as 0.2 (unless your chance of seeing a hottie is a miserable 0.2%.)
Chance You Get the Hottie's Number (%):
Assuming you meet a hottie, how good are your pimping skills? What is the percent chance you will get a hot date out of the deal? Again use a percent, not a fraction.
Value of the Hottie's Number (If You Get It):
So you picked up a hottie. But on the way home, you lose the phone number! How much would you pay God (or whomever) to remind you what the number is so you can finally score? Put that amount here.
Interest Rate (%):
What percentage interest would you expect to earn on your money over the next year (assuming for the moment that you have any)? What percentage interest do you pay on debts (credit card, etc.)? Select the largest percentage and put it here. NOTE: Type only a number (e.g. 5) and not a fraction (0.05) unless your interest is truly 0.05%.
Number of Boxers You Own Now (Best Guess):
Obviously if you wear briefs or whatever, count those too.
Your Age:
If you're 99 and going to die tomorrow, it doesn't make much sense to buy 50 pairs of boxers today, does it grandpa? Like with most things, it pays to be young.
