Doctor sits on press - these might see the funny side (8)
I believe the answer is:
ironists
'these might see the funny side' is the definition.
The definition suggests an adverb but the answer is not.
'doctor sits on press' is the wordplay.
'doctor' indicates an anagram.
'on' means one lot of letters goes inside another (as in clothing 'on' a person).
'press' becomes 'iron' (ironing is a kind of pressing).
'sits' with letters rearranged gives 'ists'.
'ists' going around 'iron' is 'IRONISTS'.
Can you help me to learn more?
(Another definition for ironists that I've seen is " satirical writers".)
