Cloth Carpet
A young married couple with a child recounts their journey from regular diapers, to cloth diapers, to cloth toilet paper, to— finally—their invention and advocacy of cloth carpet.  Much like the diapers and toilet paper, the couple discovered that they could save on worrying and constant cleaning if they just allowed their toddlers to urinate, defecate, and vomitate on their cloth carpet made from recycled materials, which they wash once among with a steam vac.  The go on and on about the benefits. Very practical.
