I'm a little stuck... Click here to teach me more about this clue!

'any old people' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'crazy cranky dotard and him' is the wordplay.
'crazy' indicates an anagram.
'and' means one lot of letters go next to another.
'cranky'+'dotard'='crankydotard'
'crankydotard' put after 'him' is 'himcrankydotard'.
'himcrankydotard' with letters rearranged gives 'TOM DICK AND HARRY'.
