Donkey in the water!?

"I'm dying" said one friend to the other "Take my donkey, go to town, and get the priest. The friend took the donkey and headed to town. On his way, it started raining very hard. They passed through a canal that was empty because of the drought.

The friend finally makes it to town, soaking wet, finds the priest, and they head back to the ranch.

On their way back, they need to pass the canal, but it is now flooded with water! They begin to cross, and the priest begins to pray!

"Our father, please..." and they start to go down into the water! The other man yells, "STOP, please STOP praying!!" As soon as the priest stopped praying, they rose again, and continued traveling. The priest started praying again.

"Our heavenly Father, please....", and again they started sinking! He stopped, and they rose again. Once they were out of the water the man tells the priest:

"Don't you see that this donkey is very religious, every time you prayed, he knelt down to pray with you!
