Only in this episode is it seen that Lois is of Croatian descent. This is implied by presence of Croatian flag and Croatian coat of arms in the room where dance is performed.
The dance performed in the end of the episode, called "Tinikling", is originally from the Philippines. It is performed with bamboo sticks.
Towards the end when Ida and Lois celebrate by chinking glasses they say "noroc" the Romanian equivalent to "cheers".
When Lois arrives to Ida and they start fighting it can clearly be seen that a photo of Zagreb's cathedral, capital of Croatia, is hanging on the wall.
