One time Rav Moshe Feinstein was asked to test a class of ten year olds in MTJ who had learned shnayim ochazim [no mean feat!]. When the test began the first question was "What do you do when you get home from school?"
A boy answered "Mir shpeelin ball" [We play ball].
Rav Moshe ztz"l enjoyed the answer and said "Zayer gut. Eahr darft shpeelin ball. Uber vee a Yid shpeelt ball un niSht vee a goy shpeelt ball. Nisht vee vilder chayos un nisht tzu shrayen. Eahr darft oich shpeelin ball uber vee a Yid shpeelt ball." [Very good. You should play ball. But like a Jew plays ball and not like a goy. Not like wild animals and not screaming. You must also play ball but like a Jew plays ball.]
AHHHHHHHHHHHHHHHH!!!!! Whata myseh!
