Owning Downtown Dallas - Joke

Two Texans are sitting on a plane from Dallas and an old Jewish
Texan is sitting between them. The first Texan says, "My name is
Roger. I own 250,000 acres. I have 1,000 head of cattle and they
call my place The Jolly Roger."
The second Texan says, "My name is John. I own 350,000 acres. I
have 5,000 head of cattle and they call my place Big John's."
They both look down at the Jewish man who says, "My name is Irving
and I own only 300 acres." Roger looks down at him and say, "300
Acres? What do you raise?" "Nothing" Irving says.
"Well then, what do you call it?" Asked John. "Downtown Dallas."
