I watched the Brady Bunch this morning and the Brady’s did a commerical for Safe Laundry Detergent. In the end as part of the payment for being in the commercial, the Brady’s received 2,000 boxes of Safe Detergent
Carol sighs and says “Well never use that all up.”
But I got to thinking six kids, two adults and Alice, now that’s nine people. How long do you guess it’d take the Brady’s to use up all 2000 boxes?
Unfortunately I have no idea how much a box of detergent holds. But I thought it might make for a few interesting guesses

Our household used to be six people. We used about a box a week - maybe a box every week and a half.
Let’s say the Bradys used a box a week. 2000 weeks is … 38 years.
But many of those years would occur after the kids had grown up and left the house, so Mike and Carol certainly wouldn’t be using that much. A box would last the two of them a couple of months probably.
I suppose it would’ve made great wedding gifts.
how big is the box is the first question you should ask. Is it the 24 load box? the special 36 load? or the really big 56 load?
Little boxes hardly last longer than a blink around here, but I am still going to have to agree with Carol that 2000 boxes is most definitely a lifetime supply. Too bad Craigslist didn’t exist for her. She could have set up a small enterprise earning the pay check they should have gotten for the commercial by selling the detergent.
Actually, The Safe Laundry Detergent Company pulled a fast one and the 2000 boxes were the single load size you get at a laundromat.
With all the school/work clothes plus towels and linens (3 loads a day) appx. 1 year and 10 months. 
Depends on how many episodes they reuse the old kid-uses-entire-box-of-detergent-to-clean-one-item-of-clothing gag.
As the weekly hosts of the neighborhood Golden Shower and Scat Association, the Brady’s laundry is REALLY busy.
Six months, tops.
