COMMENT | Please do not take this opener on Dr Mahathir Mohamad too seriously. The old man's latest slap at Najib Abdul Razak was quite something, is it not?

The Pejuang chairperson has described Najib's "Malu Apa Bossku" slogan to a naked man receiving a foreign dignitary and then urinating in front of the guest.

Oh dear, Mahathir, Mahathir! Even in my utter disgust and deepest contempt for a political adversary, I doubt I could manage thinking and saying aloud a Mahathir's "naked man peeing in front of a foreign guest".

Dear Mahathir, that was more than a good one. It was a terrific one!

However, with the utmost respect to the nonagenarian, I have to say that it was childishly personal. And that's the painful truth.

It was childish because I don't think slamming Najib in such a crudely obnoxious way was necessary. What Mahathir held against Najib is already well known, and there is no necessity to repeat it. This latest tirade was overboard.

There are those who also find it difficult, impossible even...
