i shouldn't but it's funny

Wrong thing of the day:

really wanting to go tell the neighbor's kids, who are slaving in the yard doing hard yardwork, about communism and the glorious revolution of the proletariat and labor unions and the such.

why is it so wrong?
their family is Croatian refugees. Yes, from the remnants of the old Yugoslavia.
"Mommy, what's a proletariat?"
"AUUUGGHH!!!"
