Whenever I go to another country, I try to learn at least a little of the language there. Hence the reason I speak a little bit of them and would never be considered fluent. Although, I am trying to become more fluent in French. Unfortunately, a lot of English speaking people take it for granted that they will find someone who speaks at least a little English whereever they go, which is usually the case.

I think in many English-speaking countries, the people would have had some form of formal foreign language classes at school, say at secondary/high school, so their knowledge of another language besides English is not zilch, albeit very basic/rudimentary? I could be wrong though, just playing devil's advocate here....
I don't take polls like that seriously either, that's why I'm one of those who clicked on "One...barely. I'm struggling " (I think I was the first one).
#19 That's a very old joke, which probably exists in many versions. I once heard it ending with "French".

#23 -- That's probably true of most Americans. But almost 20% of Americans speak a language other than English as their native language, and the vast majority of those people are fluent in English (by most people's definition). So there are a fair number of true bilinguals here even if the foreign language teachers can't take credit for many of them.
#24 -- I was surprised to see no one claiming "infinity times infinity" for that reason.
Actually, two people claimed "infinity x infinity" but they account for only 0.4% , which is rounded down to zero. This might also explain why the whole poll doesn't add up to 100%.
By the way, "infinity times infinity" equals infinity.
