Enjoyable time to skilfully handle Doris? (5,3)
I believe the answer is:
field day
'enjoyable time' is the definition.
(having a field day is having an enjoyable time)
'skilfully handle doris?' is the wordplay.
'skilfully handle' becomes 'field' (as in fielding a question).
'doris?' becomes 'Day' (actress Doris Day is an example).
'field'+'day'='FIELD DAY'
'to' is the link.
(Other definitions for field day that I've seen before include "short scientific expedition" , "Military exercise - time when everything goes easily" , "Successful, exciting period" , "productive time" .)
