Well, I wouldn't have said it quick like "Oh mah gawdssss" (It would have been like "Oh - my - [moderate profanity] - [secondary profanity] - god", 'cause I'm no hard cusser).
(And I've never fainted, so I don't know what I would say before I fainted, but I think it would be more like a "hah" then a "waaaaaaaaay..." then "uh")
But SERIOUSLY? I'd like a word with whoever wrote that summary (please tell me it's not in the banner/headline, just in the little synopsis) and the editor of that specific catalog. I have some hard questions for them to answer, one on each of my fists.
OK, maybe not quite that level, but I think a public acknowledgement and apology from both is warranted. Even if it's just retribution for the fanbase's outrage.
