I've checked on dejanews, and haven't been able to find this topic, so perhaps someone can answer this question. On the episode earlier this year, with the fur coat and the purse, is the girl who Jerry is dating the same girl in the Dockers commercial in the crowded subway. She has a very strong resemblence to the girl in the commercial, and she notices Jerry's clothes and says "nice pants", like in the dockers ad.
Thanks , Steve
