Pakistani Air Force
Pakistan just got their new Chinese fighter planes and sent a squadron of pilots there for training. "Ok, this one is easy to fly", said the Chinese trainer, "even you fools should be able to operate it! You press this button to go up, this one to go left and this one for turning right!"
"But how do we come down?" asked Capt. Arfath Pasha. "Oh," said the Chinese "leave that to the Indian Air Force!"
