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 asks with an incredulous look, "Don't you have any
grasshoppers in Texas"?
