"Any topic that he chooses is likely to wind somebody up."

not true. if he's supposed to be funny and "send himself up" he's got plenty of personal foibles that could draw a lot of yuks. a little "misarticulation", a few of those goofy smirk poses, some jokes about how much a rich guy like himself knows about an average person's life, national guard service, etc. heck, i could've written his stupid routine myself!
but when he starts making jokes about the lies (his lies) that have cost hundreds of american and thousands of iraqui lives then he's long past bounds of good taste. the guy is clueless, tasteless, and heartless. and i really don't understand how people hear stuff like this and don't think of the families of the dead. including the media morons who were guffawing at the dinner. no wonder this country is in the state it's in.
