I'm not even the tiniest bit Polish, however I would like to see how good I am at thinking like a Polish person, so I'm going to take a stab at answering your question the way I think a Polish person would answer it. The answer, IMHO, is: None. Because woodchucks don't chuck CHUCKS; they chuck WOOD. How's that - did I get it right?
No no no, that's all wrong. The way you would answer that in true Polish fashion would be to wake up at 4am, go to work for 14 hours, come home and eat some pigeon dumplings, chop some firewood, move some heavy stones, change the timing belt on your car, and forget all about the question because you "have no time for playing."

This is the right answer, between tending the lawn and garden, working and home nobody has time for such nonsense, dupa
