An Englishman, an American and a Scotsman wander in the desert

After a long while they encounter a huge wall. They try to go around it, over it, but the wall is too high and too long. Out of nowhere, a genie appears. The genie sais: "You must all tell a lie in order to break this wall. The greater the lie, the greater the damage. But beware, each one of you only has one try."

The men sink into deep thinking state. After hours of thinking, the Englishman begins: "Us, the english gentlemen, never drink tea with milk."

The wall cracks.

The American adds: "Us, the american gentlemen never smoke stogies after a hard day of work."

Again, the wall cracks.

Now all left up to the Scotsman, he takes a deep breath and starts: "Us, the scottish gentlemen-"

The wall shatters.
