spread 'em

Every time I hit ?s on spreads I get bent over…no matter how many times I’ve looked at the material. Anyone have anything good on remembering what each one measures/doesn’t measure?

We need Dr. Ken U. Spreadhem, Gynecologist to the rescue…

Paging Dr Proctologist, please report to the rear exit. Sorry ng, I don’t want to screw up your thread.

hey i was practically begging for it…anybody got something though?
