I'm calling bullshit on the Polish version. All the others have the same characters, more or less the same house layout, most titles are literal translations, some even recicled scripts... but the connection with the Polish one is that... both are about some dysfunctional family? That is true for about half the sitcoms of the last 25 years. You could as well call it a Polish Roseanne, a live-action Simpsons, a muppet-less Unhappily Ever After, or even [gasp!] an original take on an overused sitcom formula.
