Polish, Ukrainian and Russian babies get mixed up in the hospital Now, parents are trying to figure out which baby belongs to which parent. Ukrainian decides to go first and yells "Slava Ukraini!" One baby immediately jumps up and pulls into the attention position. Ukrainian knows that's their baby and picks it up. Polish takes the second baby and Russian looks completely confused. "How did you know the second baby is yours?" asks the Russian. "The one who smiled when Ukrainian yelled is mine" Polish answered, "but the one who wetted the nursing bed, is yours."
