Fosters beer advert that spoofs a charity add

[hammertime]

Does anybody know where i can find the fosters advert that spoofs a charity advert. It was around the late 90's.... The advert had an old african guy digging in the sand to try and find a frog to squeeze out moisture out of as there was no water... the advert then pans to his son stood a a bar driking a pint of fosters who says 'dad never was the sharpest tool in the box' I think i may of been banned.

Thanks
