I saw this commercial years ago. It starts out in a bar, with three guys having a beer, and suddenly this (kinda catchy) music starts playing and time seems to reverse, and everything around them starts to devolve, including the guys.

As the Earth devolves thru the eons, our thirsty men devolve into primates, maybe other more primitive animals, then finally into salamanders at the edge of a muddy watering hole. The salamanders then go "bleh!". And then, I think, a narrator says something like "Worth the wait", referring to some beer.

Also, I don't know if it has anything to do with it, but I think "Una Brita" was in the name of the video of it I saw, but I'm not sure.

So, does anyone know or remember this commercial, and it's subject? And, is it available to view online (link or other reference)?
