Wowza, those are some knee stains. Very specific and symmetrical. This Spray-n-Wash commercial from 1970 features a bubbly vision of sunshine that looks suspiciously like Betty White. I never remember my jeans being "permanent press" - that sounds a little high maintenance to me... but what would I know, I was an infant in 1970. Textile technology has come a long way in 40 years... yet ironically, I still use Spray-n-Wash. And I bet Betty White does too.
