A Texan came Down Under for a holiday, and was being shown around one of the cattle stations in the Northern Territory. As they were driving along, the Texan pointed at a cow and asked what it was. The station owner said, "That's one of my prize Hereford heiffers."
The Texan said, "Shoot! That one wouldn't even be weaned yet back in Texas!" A little while later, the Texan pointed at a ram and asked what it was.
The station owner said, "That's one of my stud Merino rams."
The Texan said, "Sheeoot! That ram is smaller than one of my new born lambs back in Texas!"
By this time the station owner was pretty pissed off, and when the Texan saw a mob of kangaroos and asked what they were, the station owner replied, "Grasshoppers...Incredibly LARGE grasshoppers..."
