Gareth Morgan Investments has been purchased by Kiwibank.
In some ways it's good to see KiwiBank growing, but my main reason for the post is to link to Led Zeppelin's video on youtube (about 2min 30s).
The phrase "a monkey on my back" is used by Mr Morgan to describe one of his motives for selling GMI and features in the song too, though the context is quite different; originally it referred to a drug addiction. Rather than open myself up to suggestions of pedantry, I'll run the hypothesis that the meaning has been broadened to refer to a burden, instead of an addiction. Even though UrbanDictionary is not fully supportive.
