As it's no longer politically correct to direct a joke at any one racial or ethnic minority, try this one:
An Englishman, a Scotsman, an Irishman, a Welshman, a Gurkha, a Latvian, a Turk, an Aussie, a German, a Yank, an Egyptian, a Jap, a Mexican, a Spaniard, a Russian, a Pole, a Lithuanian, a Jordanian, a Kiwi, a Swede, a Finn, a Canadian, an Israeli, a Romanian, a Bulgarian, a Serb, a Swiss, a Greek, a Singaporean, an Italian, a Norwegian, an Argentinian, a Libyan, a Muslim, a Hindu, a Buddhist and an African went to a night club.
The bouncer said, "Sorry, I can't let you in without a Thai. "
