An American walks into a bar. He finds an Iranian man sitting at a table.

He asks the Iranian man, "Are you one of those Ians?".

The Iranian replied, "What do you mean, Ians?"

"Indians, Iranians - all are the same."

The Iranian paused for a while. After that he asked the American, "Are you one of those keys?".

"What do you mean, keys?"

"Donkeys, Yankees - all are the same too."
