I don't remember where I read it, but what impressed me the most was the following story:
The researchers would celebrate the chimp's birthday's with all the chimps, and they'd also celebrate christmas with a christmas tree with candy.
One chimp, after some years, remembered that Christmas comes two days after another chimp's birthday. And on Christmas day, he went to the researcher and made the sign for 'tree' plus the sign for 'candy'.
These kind of things, which seem to happen in more than just one instance, shows true understanding, not just imitation.
