My favourite crossword clues:

Cool, OK? (8,5)

This one from the Guardian a few years ago:

Damn'd siesta! My God, I'm not Gunga Din! Heel, hounds!

(3,4,3,10,2,3,2,3,3-3,3) ....

OK, you haven't the time or patience for this sort of stuff. So the answers:

First one: absolute zero (from the Kelvin scale)

t'other: it's just one giant anagram..

mad dogs and englishmen go out in the mid-day sun.
