Keeping with the spirit of all the international jokes, I present one of my favorite Ukrainian ones.

A Ukrainian man and a Russian man are out fishing when suddenly the Russian reels in a golden fish.
The fish looks at the men and says "Congratulations! You have caught me and know I shall grant you both three wishes."
The fish turns to the Russian man and says "Since you are the one who reeled me in, you get to go first."
"Alright," says the Russian, "I wish that all of the foreigners in Russia were gone."
"It is done."
"Now, I want a massive concrete wall surrounding all of Russia so that they cannot get back in."
"It is done."
"Finally, I wish that all Russians from around the world returned to their glorious motherland."
"It is done." And with that, the Russian disappeared.
The fish turns to the Ukrainian and says "Now for your wishes."
The Ukrainian asks "Are all of the Russians in Russia?"
"Yes."
"Only Russians?"
"Yes."
"And there is a large wall surrounding all of Russia?"
"Yes."
"Then I wish for you to fill it with water."
