A man hears a knock at the door.

He opens the door and there is no one there so he closes it and walks away.

A few moments later there's a knock at the door. He opens it and finds no on there. Just as he goes to close it again hears a sound.

"I'm down here!"

The man looks down to see a snail on his doorstep.

The man asks the snail, "why'd you knock on my door?"

The snail replies, "well I've been living in the garden in front of your house for a few years now and I knocked to ask you a question. Would I be able to come and live in the house with you?"

The man suddenly yells at the snail, "NO!" And with that he gives the snail a hard kick. The kick sends the snail flying past the garden, across the road and onto the doorstep of the house opposite.

Days pass, weeks pass, months pass. Almost a year goes by and the man hears nothing from the snail. He begins to wonder if he had killed the snail or the snail had simply forgiven him and moved on. Then at that moment there's a knock at the door. The man opens the door to find the snail looking up at him.

The man looks at the snail and says, "yes?"

The snail replies,

"WHAT'D YOU DO THAT FOR?!?!"
