It took me a few to remember how OBL took credit for USS Cole, but if I recall correctly now he had released a video either shortly before or shortly afterward where he's featuring a Yemeni knife and a map of Yemen in the background. He praised the 'daring' of the attack (or however he worded it) and rambled on about how the perps were now in heaven and how the US should expect more of the same, or something along those lines.

Yes, that sounds right. I remember for quite a long time after that attack, there was no 'credit' being taken, and there were several pundits who said this was evidence it was Al Qaeda, because they often didn't take credit for attacks, but rather would not (or, sometimes, much later would make an oblique mention, as they eventually did with Cole).
