What's weird about American paper bags? In a landfill, they are pushing up daisies in 2 or 3 years. Our EU polythene monstrosities last for about 600. And the handles snap anyway! I believe Eire have a tax on them now to discourage their use.
In the good 'ol days, anyone remember 'carrier bags'? Nice stout heavy brown-paper bags with string handles. When they started charging a penny for them, my dear old Ma turned them inside out. When the cashier at the local Co-op questioned this, she replied to the effect that She wasn't paying to advertise them up the blinkin' High Street!
As to that plug and socket, Doc Brown could have picked that up anytime between 1875 and 2050.
