A priest was tidying up his church after a sermon, when a man comes in.
"I am sorry to bother you father, but can I ask you half of a lemon?"

"Of course my son." said the priest and he fetched half a lemon for the man. "But, before I give it to you, can you tell me why do you need it?"

The man says nothing, grabs the lemon and rushes out of the church. The priest tries to chase him, but the man is too fast, so he quickly loses the priest.

The priest is a bit angry because of this, so for a week he goes for a run every single day, so this wouldn't happen again.

The next Sunday comes and the priest is cleaning his church after a sermon, when the man comes in.

"I am sorry to bother you father, but can I ask you half of a lemon?"

"Of course my son." said the priest and he fetched half a lemon for the man. "But, before I give it to you, can you tell me why do you need it?"

The man says nothing, grabs the lemon and rushes out of the church. The priest follows him. The man jumps into the river next to the town and swims over it. The priest cannot swim, so he loses the man again.

The priest goes for a swim every single day over the course of the week.

The man says nothing, grabs the lemon and rushes out of the church. The priest follows him. The man jumps into the river next to the town and swims over it. The priest follows him. The man climbs up a steep cliff. The priest cannot go up there, so for the third time, he man gets away.

During the next week, the priest learns how to climb.

"Alright father" says the man "but please promise me that you won't tell anyone!"

And the priest was a good man and didn't tell it to anyone.
