I have forwarded the links to these threads, plus an explanation, to Barbara at Snopes.com, and requested that she look into it for us. IF Energizer DID change the ad, I would certainly want to know, so that I can send them a "Thank You" and make sure I buy their products in future.

(Barbara also looked into the "Swiffer" rumour and published the results here , so hopefully Snopes can clear this up for us too!!
