Yes, I realize you have toffee, but it's not really the same.
In any case, I learned that through QI. The question was "What is a taffy pull?" and I thought it was a trick question. But apparently it really was just referring to taffy, but only Rich Hall knew because he's American.
Also, as I've been watching every episode of QI, I've thus far found two things they've been wrong about. The first is "How many moons does earth have?" and they originally claimed there were two, the second being Cruithne
. However, it's not a moon. For one, it doesn't even orbit the earth. Rather, as wiki will tell you, it's a quasi-settelite. Stephen Fry also claimed that it'd been discovered in 1994, when in fact it was discovered in 1986. They revisited it in a later episode, this time claiming there were five. They added three other quasi-satellites that had been discovered in the interim, but still claimed they were moons. Stephen even said "Some people say they aren't really moons, but on the other hand what could you call them? They orbit the earth and they are, to some extent, our moons." So, yes, very wrong on that one.
The other one was when they were discussing the platypus and Stephen claimed they were "the only mammal on earth that has venom". But, while they are indeed very rare, there are several others
Edit: Actually, I just remembered one more. Alan said "Switzerland has four official languages, none of which are used on their stamps." and Stephen correct him, "none of which is
used". However, either is acceptable.
Edit 2: And I just watched him get a fourth thing wrong. He claimed marsupials aren't mammals.
