This old couple pulls into a filling station to get some gas. An equally old attendant comes out to meet them.
Attendant: "What can I do for you folks?"
Old woman: (loudly) "What did he say?"
Old man: "He said, 'What can I do for you.'" (to the attendant) "Fill 'er up."
Attendant: "Where you folks from?" (asking as he's pumping the gas)

Old man: "He asked where we're from. (to the attendant) "We're from Dallas."
Attendant: "Hmm. Worst lay I ever had was in Dallas"
Old woman: (even more loudly) "What'd he say? What'd he say?"
Old man: "He says he knows you . . ."
