"Travel In Far East" joke

Mueller is traveling with his wife and mother-in-law in a far east country. At a place of honor his mother-in-law makes a careless remark, which the native people take as an insult to the royal family.
Mueller is dragged off to court with his wife and mother-in-law and are sentenced to corporal punishment. Each of them are to recieve 50 lashes on the rear end with a cane. But because the royal family doesn’t want to appear hostile to foreigners, they grant the guests in their country a wish beforehand, as long as it is able to be fulfilled.
Mrs. Mueller is first.
“What do you wish for yourself? ”
“I would like a pillow bound on my rear end before the lashings. ”
“Okay, that shall be granted to you. ”
Mrs. Mueller has the pillow bound to her rear end and receives her punishment. But because the pillow is too small and the executioner also hits her back a couple of times, she receives a few blows.
Next it is Mueller’s mother-in-law’s turn.
“What do you wish for yourself? ”
“I would like a pillow bound on my rear end and a pillow bound on my back before the lashings. ”
“Okay, that shall be granted to you. ”
The mother-in-law receives her fifty lashes, but hardly feels the pain through the pillows.
Then comes Mueller himself.
“What do you wish for yourself? ”
“I have two wishes. Do you want to fulfill them for me? ”
“Because you are a guest in our country, we want to fulfill your wishes for you, as long as they are reasonable. ”
“I would like 100 lashes instead of 50. ”
The executioner is surprised, but recovers again right away and replies, “Yes, that is a pious wish, it shall be granted to you. And what is your second wish? ”
“I would like to have my mother-in-law bound to my back. ”
