I think it is Ameriquest that I am trying to think of, anyway, they are the best out there right now. There was one that came out during the 2005 Superbowl where a guy is making dinner, chopping up something and a white cat jumps onto the counter spilling his sauce everywhere, he gets a hold of the cat (covered in red sauce) while he has the knife in his other hand right as his girlfriend walks in the door and it looks like he just slaughtered the cat. Another one that came out during the 2006 Superbowl for the same company had 2 doctors standing over a patient, a fly is buzzing around and the doctor uses one of those paddles to zap the fly. The fly lands on the patient's chest and the doctor looks down at it and says "well, that killed him" just as the patient's mother and daughter walk in so it looks like he is talking about the patient. Both of the commericals say something along the lines of "Don't Judge Too Quickly" at the end.
the claymation one about smoking being gross is just that--but it gets your attention. A claymation guy and girl are on a couch in front of a tv with a rug on the floor. A cat comes up and pukes on the rug. The guy goes and picks up the puke, puts it in his mouth and expects the girl to kiss him. YUK!!!
