Years ago we had a brown envelope through the letterbox which we opened, not realising it was addressed to the son of the couple we bought the house off. It was a catalogue for mucky DVDs and one of them was Oral Sex On Ice
This is years before Dancing on Ice and that sort of reality show.
The Dutch postmark should have alerted me
