Er... say again?

There's a rather odd and confusing ad on the train platform right next to my apartment that has been bugging me for months. It makes very little sense, and I see it every day. At first, I'd assumed it would be replaced within a month or two, but it's been up there since the winter. I think I'm beginning to go insane, slightly.

The ad is for one of the lastest MegaCitiCorpFirstThirdNationalCommercialFederal Banks. It consists of a single phrase: "Have your dollar bills been more places than you?"

I've been trying to puzzle this out. Are they trying to get me to travel more? Perhaps since my dollar bills have been lots of places, I'd like to go there, too. But the sweaty, dark pockets of a bunch of people (or dark cash registers) just don't seem like ideal vacation spots.

Is there something wrong with money that has been through a lot of wallets? It is worth the same as a crisp dollar, right?

Then I got to thinking that they meant it as some sort of sexual innuendo. Y'know, saying someone's "been around" can have certain connotations depending on the context. But I really can't wrap my mind around the concept of promiscuous dollar bills, or why I would care (or wish to emulate them).

I haven't switched banks yet. Perhaps this is just another example of my lack of marketing savvy.
