Ham-math:  Any multiple of my size is my size.  So 6, 12, 18, 24 its all the same to those doughnut dirigibles. They will pick whatever number is convenient or desired and blubber about it.  eg  Im a 6, but this 6 doesnt fit, make it bigger... or  Marilyn was a size 12 and so am I, now you must lust after me.   or Im not a size 28, surely Im a size 24, make it bigger...
