'jokes' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?

'a crew's involved with sick' is the wordplay.
'involved with' is an anagram indicator (involved can mean confusing or complex).
'a'+'crews'='acrews'
'acrews' with its letters mixed up with 'sick' gives 'WISECRACKS'.
