Spork pointed out to me that she'd heard the much-criticized Teen Talk Barbie apparently didn't say, "Math class is hard." Instead, she said the slightly less pithier phrase "Math class is tough."

Which I thought was odd, because I was pretty sure I'd only ever heard the latter phrase (and used it frequently enough that Spork gave me the jar of Barbie heads above with the comment, "I thought you'd like this"). And a guick google search showed 13,000+ plus hits for "Math class is hard," but only 595 hits for "Math class is tough." However, hits on the Wikipedia article showed up for both variations.

Helpfully, the discussion page on the Wikipedia article included a mention that "math is tough" seemed to be a widely repeated urban legend. And for the "math class is hard" variation, referenced in the main page of the Wikipedia article included a source for the "math class is tough" quote, to this 1992 article at New York Times, which includes a quote from Jill E. Barad, then president of Mattel: "In hindsight, the phrase 'math class is tough', while correct for many students both male and female, should not have been included."
