If here on fluther we had a famous guest for the day, who would you like it to be & what question/s would you ask them?

A slightly different angle from that of my previous question, which revolved around a talk show format. Yeah, what if someone famous were actually on these pages…...there may already be, I dunno. Maybe your favourite musician or movie star. Anyone you fancy really. For the sake of this question we’ll stick with the living, they smell better anyway. How many of your allotted 3 questions would you use up on them? Of course you may have absolutely no desire to interact with a “celebrity” on here, or anywhere else for that matter.
