An Englishman, a Frenchman, a Spaniard, and a German went to see a show...

The four of them went to see a man on stage. The problem is, the stage was a bit high, so they might have trouble seeing him. As the man went on stage, he said, "Can you see me?" They all replied:

"Yes."

"Oui."

"Sí."

"Ja."
