keep in mind that cornerstones, in general, take getting laid a lot less seriously than, say, high-school juniors

You have got to be kidding!

Even a cursory study of the subject will tell you that cornerstones exist to get laid. Granted, most of them do it only once, and then just lie their quiescient for the remainder of their lifetimes; but to get laid is the be-all and end-all of a cornerstones existance.

JUST like most high school juniors.
