I can't follow a programme for long enough if I have them off (I'm hard of hearing rather than deaf deaf) but sometimes the mistakes on them are so distracting I'm not sure what's worse!
A recent one, BBC Breakfast:
"Do you know you're double negatives from your split infinitives?"
Sort of let that off as it's live, but still distracting!
One of my pet peeves (MN seems bad for it) on one programme recently, not live so no excuse IMO "antinatal"
