What I remember about this commercial is that the very last line was, "Buy some for Lulu!" Well, I either misremember it, since this was also a tag line for Smarties candy, the Canadian version of M&Ms. Or, since Smarties were made by either Rowntree's or Nestlé's, it could be that Milk-o was too, and they capitalized on the tag line, which was very well known at the time. Well, that's all I've got.
