My favourite was one that ran here in Canada at least fifteen years ago. Featured a cow singing in a cheezy lounge lizard style, "You'll never know, how much I love you" and finishes with an Elvis style "Thank you, thank you very much". The tag line was "HP Sauce, it makes beef sing".

As much as I detest seeing the Nike slogan in Hockey, their ads a few years ago featuring NHL Goalies in full equipment, masks and all working at menial jobs because they had been put out of work by the Nike staff players. My favourite was the Chicago Black Hawks goalie working behind the counter at a burger joint. Two guys step up to order, say to him 'hey, aren't you so and so?' and he goes into a tirade about how he was an NHL star until that Mats Sundin exposed a weak glove hand. He is screaming "a weak glove hand, a weak glove hand" (think Arlo's Kill, Kill) and banging his hands on the counter. The customers turn to leave to get away from him and as they are walking to the door he shouts out "hey, I was employee of the month".

There was another one with a former goalie as a New York City cab driver that was also very funny.
