This reminds me of one of my favorite dirty-mind stories...when the kids were little they had one of those Winnie-The-Pooh travesty Disney spinoff books with the strip of sound effects down the side, and when you pressed the Tigger button you heard Tigger say, "THAT is what Tiggers do best!"
But at one point we realized it sounded like it was saying "FUCK is what Tiggers do best!" And after that, it was impossible to un-hear it. Imagine sitting around with one's parents hearing this phrase over and over, nodding and grinning as though nothing untoward is going on.
