I remember them.

Along with the paper underpants that were the fashionable gimmick at the time. No laundry, just throw them away. Mother thought they'd be useful for camping.
They were not remotely practical for a child bouncing on a trampoline.

That was not the pair that came wrapped around my copy of Alice Cooper's "School's Out", although I was made to use those ones too.
We had no idea they'd be worth anything later.
