The whole thing was just basically RW doing his standup routine
Did you guys realize how Robin Williams was pretty much doing his standup material in most of the scenes? I mean, I know he uses the same jokes all the time, it's obvious from his talk show appearances, he even reused some on his latest DVD from the 2002 Broadway DVD..
But if you've seen the 2010 Weapons of Self Destruction DVD, there he talks about the ethanol car, helium car, all that stuff that's in this movie.. The Brazilian pope also comes to mind from somewhere maybe from the same DVD or just some talk show he did..but basically 99% is his own material.. not cool. It's not that they're not good jokes but he (or the scriptwriter) should have written new ones, some fresh material. Or maybe Robin should stop using jokes for years and years, stop being lazy. I know many comedians do this, hell even Bill Hicks was doing the Kennedy joke for pretty much all his career, but still, a new joke here and then would not hurt anybody.
