How possible.....???????

Guy: Doctor, My girlfriend is
pregnant but we always used double
protection. Then, how is it possible?

Doctor: Let me tell you a story to make you realize that it is possible.

"There was a Hunter who always carried a Gun wherever he went.

One day, he took his Umbrella instead of his Gun and went out.

A Lion suddenly jumped infront of him.
In order to scare the Lion, the hunter used the Umbrella like a Gun and shot the Lion, the Lion collapsed & died!

Guy:This is totally Nonsense!!

"Someone else must have shot the Lion"

Doctor: Good!! You understood the Story.

Next patient please......
