Is the telephone chord to your headset all twisted?

I better give you this advice right now. It’ll be obsolete soon when everybody uses wireless phones only.
If the chord from the telephone to thing you hold in your face is all twisted: disconnect at one end or the other (usually easy to do), hold the heavy piece in your hand, and the chord will untwist in a moment.
That chord usually gets twisted because you give it a turn in the process of picking it up and putting it back. See if you can catch yourself doing it!
