Swap the speakers

As the Buzzcocks once succinctly observed: noise annoys

 – and it's even more irritating when you can't stop it.

To pull off this brand of hi-jink, simply take your target's

speaker cable and plug it into your PC instead of theirs.

Now anything you play on your PC will come through their speakers,

whether it's novelty pop songs, death metal or an array of silly sound effects.
