Wally was just repeating one of Walter's quotes from the movie...

Walter Sobchak: Those rich fucks! This whole fucking thing... I did not watch my buddies die face down in the muck so that this fucking strumpet...

The Dude: I don't see any connection to Vietnam, Walter.

Walter Sobchak: Well, there isn't a literal connection, Dude.

The Dude: Walter, face it, there isn't any connection.

Don't worry. Walter has that effect on everyone. That's what makes him such a great character.

Walter Sobchak (played by John Goodman) has that effect on everyone, because he's always stirring the pot. That's what makes him such a great character in The Big Lebowski.

Well, this is a very complicated case. Lotta ins, lotta outs, lotta what-have-yous.

Well, okay, you're not privy to all the new shit, so uh, you know, but that's what you pay me for. Speaking of which, do you think you could give me my 20 thousand in cash? I gotta check this with my accountant of course, but my concern is that, you know, it could bump me into a higher tax bracket.

Okay, vee proceed, but only if there is no funny stuff.
