A man from Spain visiting the US walked into a clothes store. He said to the clerk, "Quiero comprar unos calcetines, por favor." Unfortunately, the clerk didn't speak Spanish, and the Spaniard didn't speak English. They searched all around the store, the clerk pointing to various items, hoping to find what the foreign customer wanted.
He pointed at jackets, but the foreigner shook his head and said "No quiero chaquetas." Then he pointed at shirts, but the client was not satisfied and said "No quiero ni camisas." The clerk pointed at sweaters, pants, shoes... but the Spaniard said he didn't want "ni sudaderas, ni pantalones, ni zapatos...".
They couldn't come across the item the shopper needed. Finally, the clerk points to a table of socks, and the man from Spain exclaimed with joy, "¡Eso sí que es!" The clerk exploded in anger, shouting "If you could spell it, why didn't you say it before?!"
Lohn is German for wages.
