(I found this joke on a Texas website but it had a prefeace that I should also repeat here.

Barrie J. Wright of Adelaide, wrote that this joke was current in WW2 "when we fought together")

Two Texans get off the plane in Sydney. One Texan had been to Australia before and is cautioning the other.

"Now look, the Aussies are not so bad. They're a lot better than the damyankees -but they do have some peculiar ideas. Don't pick a fight with them because they do take offense at lots of things that you and I would laugh off as just plain stupid."

The other Texan says: "Like what?"

The first Texan says: " Well, don't argue with them when they try to tell you that Australia is bigger than Texas".
