re: Actors you imagine are douchebags IRL

Met some people while working in the French Quarter:

Paul Shaffer. Snooty little bastard.
James Cameron is a prick and a half.
Both Anthony Kiedis (RHCP) and Micky Dolenz (The Monkees) came across as guarded and leery.
Jeff Blauser (ATL Braves): Anal retentive family guy, if that makes any sense

Kevin Dillon is cool as frick. Approachable dude looking to have a nice time. Reminds me of Dave Grohl.
GW Bailey, ironically who played the a-hole Lt Harris in all the Police Academy Movies is by far the nicest star I ever met.
Eddie Money: Family man, and as unpretentious as you can get.
Alexandra Paul (of Baywatch): Down to earth, engaging, and courteous.
