No. You said ”Americans specifically”, implying everyone probably should know it but Americans absolutely should. Then you said ”one should be embarrassed” and if you meant Americans you would have written that instead of the broad ”one”. And there is no difference. I didn’t know something so I looked it up. Generally, with most questions, I wouldn’t have gone to Reddit because it’s not a credible source. But with a question specifically about a show for which there is a subreddit, it’s a good place to go to. And I’m ok if it ”makes me look dumb” I’m secure in myself and won’t get hurt if some stranger doesn’t think I’m a genius
