What about the other flag that is not the U.S. flag?
Please be more specific. Are you talking about the New York City flag?
Bishop73
It is the Iowa State flag. At least in the episode from 1/22/21.
It wouldn't be the Iowa State flag. Plus the Iowa State flag is blue, white, and red. The flag I think they're talking about is blue, white, and orange.
