One day a flying saucer lands in the field of a farmer.

An aliens couple goes to the farmer and ask him very politely if they can hide there saucer in his barn.

The farmer thinks, well those creatures are well mannered, so why not.

So the aliens ask him if he could provide them with some food, so again the farmer agrees.

After dinner, it’s getting quite late, the aliens ask if they can spend the night. The farmer and his wife agree.

The aliens look at the couple and ask, would you be interested in changing partners tonight, like an experiment?

The farmer and his wife look at the aliens who both look quite sexy, so they agree.

The next morning, as the aliens have left the farm, the farmer asks his wife:

“ you just can’t stop smiling, was it so good?”

“ Well I took the alien man upstairs and we undressed. As I pulled his pants down I saw he had this very tiny thingy hanging there. I must have looked disappointed, but he took my hands placed the on this ears and asked me to pull them. So I did, and his thingy blow up to twice the size of a human man. It was the hottest night I ever had!”

The farmer starts looking sad, so his wife asks what’s wrong!

He answers: “ now I know why that Alien girl kept pulling my ears all night long!”
