Question: Among the clients born between 1980 and 2000, list the name of male clients who complained through referral.
Evidence: born between 1980 and 2000 refers to year BETWEEN 1980 AND 2000; name = first, middle, last; male refers to sex = 'Male'; complained through refers to "Submitted via";

SQL:
SELECT T1.first, T1.middle, T1.last FROM client AS T1 INNER JOIN events AS T2 ON T1.client_id = T2.Client_ID WHERE T1.year BETWEEN 1980 AND 2000 AND T1.sex = 'Male' AND T2.`Submitted via` = 'Referral'
