At least to judge by this story from his blog site today about people offering him investment opportunities, one in particular whose letter he has put into the blog post.
It seems that a person was offering to sell Sir Bob one of those precious, single-letter New Zealand car number plates: in particular one, “J”, which the offerer thought Jones might be interested in given his surname. Supplied were images of the plate, complete with a little Silver Fern and the four red stars of the NZ flag.
Below is Sir Bob’s reply, on his company letterhead.

Did they come accompanied with glitter and a vial of the liquid before drying to authenticate that Sir John Key’s shit does not stink, asking for a collector mate (not seen for some time alas).
