The newspaper I work for got a phone call to tell us that a letter written to and printed in the paper had been read out on Radio Four's Newsquiz. The writer of the letter was responding to a letter sent previously to the paper, bemoaning the amount of publicity given to Bruce Forsyth's 80th birthday.
It criticised the original sender for wasting time in sending a letter to the local paper at all. The writer of the second letter failed to see the irony that she had taken the time and trouble to write to the paper to express this.
The caller to the paper also failed to see the irony of her phone call.
Beautiful.
