Stales...

Instrument of torture? Mebbe not. Mebbe it's more like acupunchorseture... You hit a pressure point that the horse ain't used to thinkin' about--it surprises the horse--and, yeah, leave it on too long, you've got problems. I mean, horses think food is supposed to go into that place--and the horse, he's thinkin', "This shore am strange food. I cain't taste it, and it's not comin' in. What izz this food doin' there kinda stingin' me like Vietnamese hot pot?" And the horse, he jes' keeps on thinkin' about this immovable feast, wonderin' when it's gonna come in, jes' plain pushed past his horse sense treshhold...and you, you git done what needs gittin' done.

That's my take on it.
