The G20 are meeting in Pittsburgh, so I think it's appropriate to post some dialogue from "Sullivan's Travels" about that fair city.
LeBrand and Hadrian are studio executives, Sullivan is a director of light comedies who wants to make a serious picture of social import. They are discussing another such picture.
LeBrand: It died in Pittsburgh.
Hadrian: Like a dog!
John L. Sullivan: Aw, what do they know in Pittsburgh...
Hadrian: They know what they like.
John L. Sullivan: If they knew what they liked, they wouldn't live in Pittsburgh!
Here is the nine-minute sequence that includes the quotation above, from, like I said, "Sullivan's Travels," one of the greatest comedies of all time.
