A Texan farmer goes to Australia for a vacation. There he meets an Aussie
farmer and gets talking. The Aussie shows off his big wheat field and the Texan
says, "Oh! We have wheat fields that are at least twice as large."
Then they walk around the ranch a little, and the Aussie shows off his herd of
cattle. The Texan immediately says, "We have longhorns that are at least twice
as large as your cows."
The conversation has, meanwhile, almost died when the Texan sees a herd of
kangaroos hopping through the field. He asks, "And what are those?"
The Aussie replies with an incredulous look, "Don't you have grasshoppers in
Texas?"
