Unfortunate trip

3 people were going on a trip all around the world with their private aeroplane, but just above some Indian colony the engines stopped working and they fell to the ground. Surprisingly, both 3 people lived without a scratch. But as soon as they got out of the plane, they saw the Indians standing around them. They tied them up with some ropes, and took them to their leader.
Their leader said to the prisoners, 'Each one of you will tell a joke. If the whole village laughs, we'll let the person go. If not, then we'll cut off his head'.
The first person tells a joke, and luckily the whole village bursts into laughs. They let him go.
The second person tells a joke, and again the whole village starts laughing. He is allowed to leave too.
When the third person tells a joke, the whole village starts laughing, except one single person. They don't let him go, and they cut off his head.
A few minutes afterwards, they see the person who didn't laugh earlier laughing with great pleasure.
They ask him, 'What are you laughing about? You didn't laugh earlier when the person told the joke'
And he replied, 'Now I get it'.
