Whoops I'm guessing from your post the only people are going to get the reference are probably Brits.
Lord Sugar is to the UK 'The Apprentice' TV show what Donald Trump is to the US one and Mark Bouris is to the Australian, namely the grumpy man who sits in the chair telling people "you're fired!"
Here's his bio on the bbc site:

It ocurred to me earlier that as grumpy as he can be (I see him as the King of Swords), I reckon he'd take any information he could get his hands on. Tell you it was probably useless but end up thinking about it privately at a later date and probably putting it to good use, hence I started wondering if he'd ever gotten a tarot reading.
Plus it tickled my fancy to think of him doing his usual "oh get on with it, I haven't got all day, I'm a busy man, cut to the point" to a reader who was trying to do a celtic cross on him, OR to a reader who wasn't very good going "nah not for me, you're fired" OR him being utterly dumbfounded (and shut up) by the accuracy of a reading.
