This situation doesn't seem too promising. Let's look around for some lower hanging fruit

For whatever reason, you have a feeling that if you stay talking to these two, you'll end up with nothing but a pair of blue balls at the end of the night. Telling the two of them it was nice to meet them, you come up with some weak excuse of why you can't stay to talk and make your way towards the opposite end of the bar.

Even though those two didn't work out, there were still two other pairs of women you had seen before that had gotten your attention. Looking around, you see that neither pair has anyone else talking to them, so you figure you've still got options available to you.
