Aw, shucks, Michael, it's hard to explain, but I'll try...

Is it my good looks? My money?

Is it my prodigious talent? My scintillating wit?

Is it my black belt (7th Dan) in Judo?

Is it my connections to the noble houses of Europe?

Is it my multifarious achievements in science, humanities and the arts?

Nope - it's none of these. I just make sure, when I'm down the pub, that I always stand my round.
