In the early 90s, my mom bought an apparently new bedspread from The Big K.
When she returned home, she opened it to put it on the bed, but to her surprise, there was a home job VHS folded inside the comforter.
Being the curious 20-something she was, she put the tape in the VCR.
It was fetish porn of people peeing and shitting on each other.... which had apparently been accidentally bundled into the comforter by the last people who had returned it.
Needless to say, the bedspread was returned for the second time... We don't watch unlabeled movies anymore either.
