In the beginning, there was nothing.

Then, J Bizzle said ‘Let there be MACK’. (By solving y=∞/0)

And so Mack was born.

Mack then set to work: building the Mackverse.

On the first day, Mack divided the Mackverse into the land (for macking) and the sea (not for macking, except Antwerp harbour).

On the second day Mack split time into day (for recovering and honing of tactics) and the night (for macking, of course).

On the third day, Mack made women (mackable) and men (non-mackable).

On the fourth day, Mack divided the women into mackables (>5) and non-mackables (<5). Needless to say, there were far more of the former than the latter.

On the fifth day, Mack identified targets, naming them Macks.

On the sixth day, Mack prioritised his targets, whilst remembering that a Mack's a Mack.

And on the seventh day, Mack set to his heavenly work: MACKING. Henceforth from this day no girl was ever safe............
There once was a boy with a gift
He pulled girls so incredibly swift
He simply said ‘Mack.’
Mack mack mack, mack mack.’
And began work on the holy night shift.

The 9 steps of the Mack, by Mack himself can be purchased from all good bookstores.

Note: Mack has never, will never, and can never fail!!!
