first he is being sarcastic by asking the color of the curtains [as in you’ve got it all planned out!]. and then she responds literally to reflect back his sarcasm.
The arguments about Columbus are silly. Clearly he was not the first nor even the first European to visit the Americas. He was, however, the traveler who unleashed the inclusion of the Americas into the the then known world’s orbit made up of Asia [yes, China] and Europe. As for the the old trope that Columbus was Jewish, a book by the scholar Carol Delany shows that Columbus was hoping that his journey would bring riches that could be used for evangelization of the Catholic Church. Also, I take use of Bologna in the antipasto to allude to all of the baloney his travels have accreted.
