Polish kindergarten has no clue

Oh they know. What do you think happens in a Polish kindergarten?

I remember when I was in high school and I was watching the show in class and this douchey popular guy came up and was trying to make fun of me for watching cartoons at 17, and I said oh you mean this one? And I showed him a clip where heads are getting chopped off or something and he says "oh. uh... yeah that one..." and trails off before walking away.

I don't get it

LOL
