Here is the Question:

One day,a man with his rifle went on a hunting trip. but this rifle's effective range is only 10meter, and this bird is 15meter away.
however, this man take a quick aim and open fire. next moment he found the bird dead on the ground.
so the question is how the hell the man manage to kill the bird was 15meter away, with a rifle only have a effective range of 10meter....

will post the answer later, so everyone please enjoy thinking of the answer...
here is a little hint:
it's a lame answer.

ok, since no one answer it i'll review the answer, let u guys decide whether it's lame or not.
the man able to shoot the bird at 50meter away it's because the barrier of the rifle is 45meter long!!!

Wasn't it 10 and 15 meters in the original joke? ._.
