"drink a cup, lose yer nut" is a little more apt, and certainly more frightening, not to mention detrimental to the product's sales.

if anything, it'd make a great pitch to switch to coffee "our drink is chock full of'em, and wont chop off of them." something like that.

either way, i dont see gen x'rs being intrigued.

the more apathetic wanna be generation y class, however, might lean in the direction of tea. especially with a slogan like "what the fuck. have some"
