Standard to keep cryptic clue current and funny (8)
I believe the answer is:
peculiar
'funny' is the definition.
('peculiar' can be a synonym of 'funny')
'standard to keep cryptic clue current' is the wordplay.
'standard' becomes 'par' (I've seen this before).
'to keep' means one lot of letters goes inside another.
'cryptic' indicates an anagram (I've seen this in other clues).
'current' becomes 'i' (symbol for electric current).
'clue'+'i'='cluei'
'cluei' anagrammed gives 'eculi'.
'par' going around 'eculi' is 'PECULIAR'.
'and' acts as a link.
(Other definitions for peculiar that I've seen before include "Belonging exclusively to, person or place" , "Extraordinary" , "Characteristic" , "Strange, I clear up" , "Out of the ordinary" .)
