A European pulls up at a bus stop where two Americans are waiting. "Entschuldigung, koennen Sie Deutsch sprechen?" he asks. The two Americans just stare at him.
"Excusez-moi, parlez vous Francais?" he tries. The two continue to stare. "Parlare Italiano?" No response. "Hablan ustedes Espanol?" Still nothing.
The guy drives off frustrated. The first American turns to the second and says, "Y'know, maybe we should learn a foreign language."
"What for?" asks the other. "That guy knew four languages, and it didn't do him any good."
