What is Butcher Paradox? I've never heard of it...

Very good grid. my last two were the chocolate and rolls and was just too much overlap to work it out.

Interesting how the academic themes are universal (logical paradoxes, scientists for whom elements are named), while household phrases that every British child must know (kitchen roll, drinking chocolate) are unknown to me as an American adult.
But like HughHugh, I don't know the butcher paradox, and Google doesn't help. Can anyone explain that one?
