It's meant to be a joke. Some will find it funny, but to others - David's supporters in particular - not so much.
It's fair to say if you were Joe Karam and you were tipped off about this joke you'd probably like it taken out too. Some will be shocked that he has been successful.
You might think that TV3 and the producers are simply being cowards. It's just a joke after all. Like all the ones that Letterman makes about OJ Simpson, perhaps?
A lawyer tells me the word association involved is clearly defamatory and so it's a no brainier to remove it.
Unless you have deep pockets and a real belief in your cause it pays to walk away. Which is what TV3 and the producers have evidently done.
But I can't help thinking that Karam has inflicted an own-goal by drawing attention to a joke in an edgy comedy show that's likely to have a niche audience.
Rather than thousands of viewers simply emitting a guffaw or snort and then forgetting the joke, it's now front-page news. That unlikely new word 'Lundybainwatson' is probably being screen printed onto T-shirts as we speak.
Talk about unintended consequences. Perhaps the story could even serve to put the case of Scott Watson back in the limelight. He still has a strong base of supporters and if the rather compelling book and 2003 documentary Murder on The Blade? by Keith Hunter is to be believed, he may well be innocent.
The only sensible thing to do now is for TV3 to change the name of dog to Lundyridgewatson, thus ensuring some cross-promotional synergy with the upcoming Sally Ridge reality show.
