Sometimes it’s hard to tell the difference between edgy social commentary and just plain bad English.
UPDATE: Mystery solved, at least partially. The reference is to a book, LSD on Campus by Warren Young, published in 1966. http://www.amazon.com/LSD-campus-Warren-R-Young/dp/B0007DEP42
But the script on the t-shirt says “The taskting trerk about the nather a want ceakwaererd trug and the ahe in laceining andayne and anwindrine.” The subtitle on the book cover says “The shocking truth about the nation’s most controversial drug and it’s use in American colleges and universities” an obvious reference to the 60s psychedelic drug, lysergic acid. So was someone just stoned out of their gourd when they wrote it, or is there some more boring explanation.
