I'm currently really sick of the Penfed "great rates" jingle. At the moment a lot of what I'm doing at work involves insurance rates, both those paid to providers and those collected as premiums, so it seems like I wind up with that stupid jingle in my head at some point most weekdays. I guess that means their ad agency did a good job—but on the other hand, it also means I'm unlikely ever to do business with Penfed because I hate that song so much by now.
