What I can't fathom though is his great opportunism. He literally is a weasel. For example he pretended to be wanting to buy an island (which he couldn't afford), so they met him there with helicopter and wined and dined him and his girlfriend. When it turned out he couldn't afford it they booted him out. The whole living larger than life thing and pretending to be bigger than you are is typical of ESTP. Plenty more of those stories if you read up on him. Most ESTP's I know are like that.
The stunts could either be explained by performance (ESFP) or by tacky opportunism (ESTP). ESTP's do tend to be tacky.
