A farmer from Texas goes to Australia on vacation. There he meets an Australian farmer and gets talking.

The Australian shows off his big wheat field and the Texan says,
"Oh! We have wheat fields that are at least twice that size!"

The Australian is annoyed at the Texan but doesn't say anything.
They walk around the farm a little, and the Australian farmer shows off his herd of cattle.

The Texan immediately replies,
"We have longhorns that are at least twice as large as your cows."

The conversation has died down when the Texan sees some kangaroos hopping through the field.

He asks the Aussie,
"What are those?"

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