I remember seeing these ads (perhaps just a couple of times), in the late ’90s and yet are vivid in my memory. These ads ran during the 1998 season of MLB for the New York Yankees and sponsored by Adidas.
Agency: Leagas Delaney. There are 3 spots in the playlist, with ‘ANSKY’ being the funniest. There was a fourth one too, where ‘S’ has to be replaced at the stadium.
Aside from the humour, I think it touches a chord because it beautifully captured the ‘I will go to any lengths to support my team’ attitude of the sports fan. Here’s an interesting article about making of the ad, from the New York Times archives.
