Sure. There’s a thing in a lot of languages called grammatical cases. In basic terms cases make a word “adhere” to the rest of the sentence. Different languages have different amounts of cases. For example, German has four, Ukrainian – seven and Russian – six cases for nouns.

In this case the word тракторист would change to тракториста and it rhymes with триста.

The whole joke looks like this:

— Триста.

— Отсоси у тракториста!
