Mr. Bernard heard a faint knock on his door. When he opened the door, he saw a tiny snail on his door step.

"What do you want?" yelled Mr. Bernard.

"Help me sir, I have a problem." said the snail.

Mr. Bernard then kicked the poor snail across the street with his foot and slammed the door shut.

A year goes by and there's another knock at the door.

As Mr. Bernard opens the door, the same little snail is there and asks,"Why did you do that?" .
