The editorial office is on New York, the ad production office in El Segundo, CA and we don't see the content of ads until the final review, which is the last step before that issue goes on press. In this case, the submission of this ad was so late that we didn't see it even then. So while we knew the identity of the advertiser and could ensure that the ad didn't appear near Mikey's review, we were not aware that the ad quoted from that review.
Apologies for this mishap.
