The absurdity of indirect television advertising

Do you remember the Gillette 2 advertisement that ran on TV say about a decade ago? Now what was so absurd about it? It starts off with this guy waking up late. He then rushes to catch a train. Obviously he gets off the train little later than usual. Unfortunately due to the delay he misses the girl who had been waiting for him at the station. Just then another train comes there and what happens? A girl gets off with this major fake smile.
Now tell me what has this got to do with razors or shaving?
