Halloween wasn't that long ago, so the Czech Fed Cup team understandably had some face paint crayons handy. Reporter Nick McCarvel added an extra step his quiz on American knowledge with Czechs Barbora Strycova, Katerina Siniakova and Barbora Krejcikova. 

Strycova had no trouble with the first question, while Siniakova got a little tight naming three states (New York, home of the US Open, really should have been an obvious one). By the end, McCarvel's face was covered in red, white and blue—which is a show off support to both teams, arguably.

The Czechs will face off against the Americans starting on Saturday in Prague. The U.S. team is the defending champion, but the Czech Republic has developed a Fed Cup-winning dynasty as they seek their sixth title in eight years. 

Petra Kvitova rounds out the Czech team, while Team USA features Alison Riske and rookies Danielle Collins, Sofia Kenin and Nicole Melichar.
