I was helping a friend control his wedding slides at his wedding dinner when I noticed that the sound was intermittent. Checking the audio cable connected to the notebook I noticed the cable was tight and had no slack in it. So I gave it some slack by pulling more from underneath the table. But still the problem persisted.

That's when i realized that the body of the audio plug had cracked, and seemed to be tugging on the internal wires causing the interference. With one hand on the cable I fished out my wallet and splayed it open on the table, then I reached into one of the card compartments and pulled out my duct tape stash, I managed to pull a strip out but I was unable to tear it with one hand.

So I bit into the tape to steady it and rip it out with my free hand!

Then I wrapped the tape around the plug to secure it. Boy am I lucky I have that tape around in my wallet!
