Things I've learned this week from watching QI repeats

That a rock discovered in Cummington, Massachusetts, was called Cummingtonite. Ooh er.

That, despite being a mammal, a duck-billed platypus doesn’t have mammary glands. Instead a mummy platypus ‘sweats’ milk to feed her young. And in fact, all mammary glands are evolved sweat glands. Which kind of makes most of the top-heavy girls in Loaded seem slightly less attractive.
