I changed mine from a geek (me in real life ) to the Big Lebowski (my hero, and Jeff Bridges being my favourite actor). I noticed just now that Noodley has gone from the ultra cool Fletch to a pig!!! And Melville, who used to be the cool dude from Kraftwerk to a some (no) body. And there are others too numerous to name. Why? Aren't we content with the persona we assume?
