and don'cha just *know* you're in trouble when you never dropped acid in the 60s and yet there you are havin' flashbacks and experiencing chronic weight-weenieism? (aside from, y'know, the stone seat)

Eventually the limestone seats will 'give' and 'mold' themselves to our particular posteriors.
(sounds a lot like Brooks logic to me... hmmmm...)
