On BBC's Radio 4 "Heresy" program recently, there was a discussion about throwing milkshakes at people of whom one disapproves.
Jo Brand asked, "Why bother with a milkshake when you could get some battery acid?"
I'm sure the quip provided no end of amusement for ex-model Katie Piper, her friends and family and for several other people who have been grievously harmed in exactly that way.
It wouldn't surprise me if a great many yobbos were now collecting battery acid for just such a purpose and I await with increasing horror the first evidence that any such creature has taken Jo's advice.
In her defence, it might be said that it was only a joke.
Fair enough, one might say - but one might just as easily say that Danny Baker's chimp photo was "only a joke".
On balance, however, I'd much rather someone liken me to a chimp than throw a beakerful of acid in my face, wouldn't you?
So, I wonder what will now happen to Jo Brand?
Will she be sacked as Danny Baker was sacked?
No, I have a feeling it's going to be one law for Danny and another law for Jo.
