Once a plane crashed somewhere in the mountains:

Only a monkey who was traveling in the plane was left alive.

Fortunately the monkey was intelligent enough to understand English and reply.

The officials went to see the monkey in the hospital and had a talk with the monkey.

Officer: "When the plane took off what were the travelers doing?"

Monkey: "Tying their belts"

Officer: "What were the air hostesses doing?"

Monkey: "Saying Hello! Good morning!"
