Two guys were working at the airport, when a foreigner walked up to them...
He asked them in Spanish, where the luggage pick up was.
Neither could understand him, so they raised their hands and shook their heads that they don't understand.
He asked again, in German.
Again, the two workers did not understand him.
He tried in Polish and then again in French, but both times, the employees couldn't understand him.
He walked away trying to find someone else who could help him.
One guy turned to the other guy and said, "You know, maybe we should learn a second language."
"Why would you want to do that?" replied the other guy.
"It would help out in situations like the one we just had."
"What good would knowing a second language be? That guy knew 4 and it didn't help him any."
